a definition of reference locations between the recording medium at and the scanning and / or recording head ak in accordance with fig3 precedes the description of various embodiments of the invention and this is used consistently as the basis for the further embodiments . references relating to the same objects are likewise used coincidentally in the figures . in correspondence with fig3 and using a crossing of coordinates which is based on the centre of the scanning and / or recording head ak , there are defined , a focusing direction z directed perpendicularly to the recording medium at , a radial direction x running parallel to the recording medium at and perpendicularly to the information track of the recording medium at as well as a tangential direction y running parallel to the recording medium at and along the information track . the recording medium at rotates , as indicated by a circular arrow , about an axis a , which represents the axis a of the turn - table receiving the recording medium at . in a first embodiment of the invention in accordance with fig1 and fig2 the scanning and / or recording head ak is an objective lens ol that is accommodated by a carrier t which , in accordance with the invention , is supported via resilient moulded parts f1 , f2 on a base plate bp that serves for the coarse positioning of the objective lens ol . in correspondence with fig1 the resilient moulded parts f1 , f2 are synthetic material sections which are fashioned in step - like manner , are elastically deformable in every direction and exhibit a damping characteristic which , in the desired deflection range , serves in the first place , to avoid self resonances of the vibration barrier and , in the limit positions of the deflection range , prevents a contact of the objective lens ol , or of the carrier accommodating the objective lens ol , with the base plate bp or any other stationary parts . the step - like fashioned , moulded parts f1 , f2 are arranged symmetrically with respect to the objective lens ol and to the carrier accommodating the objective lens ol at its centre and are also attached to opposite truncated corners of the rectangular carrier t . the connection to the carrier t is provided at the respective suspension of the tread of the steps formed by the resilient moulded parts f1 , f2 . on the other hand , the step - like moulded parts f1 , f2 are respectively supported on the base plate bp by the anchorage of the kick - part of the step or are connected to the base plate bp . the objective lens ol is positioned centrally over an opening o provided in the base plate bp and the individual parts are connected to each other by interlocking catch means , so - called snap - in connections , in a manner that is not illustrated . likewise not illustrated in fig1 were the manoeuvering means with which the deflection of the objective lens ol in the focusing direction z , radial direction x , tangential direction y and in the direction of the planes , which the radial direction x as well as the tangential direction y form with the focusing direction z , is effected . coils sp , which are arranged opposite the permanent magnets m and are inserted in the carrier t , are provided as active manoeuvering means . the deflection in the focusing direction z occurs in a known and not illustrated manner by means of a coil whose axis coincides with the optical axis of the objective lens ol and which has a diameter that corresponds at least to the diameter of the objective lens ol . for the deflection of the objective lens ol in the tangential direction y and in the radial direction x as well as through angles within the planes which these directions x , y form with the focusing direction z , there are provided two coil pairs which are arranged at right angles to each other and are formed by respective individually controllable coils sp1 , sp2 , of which one coil pair is illustrated in fig2 . the coils sp1 , sp2 forming one coil pair are arranged parallel to one another and respectively parallel to a pair of oppositely disposed permanent magnets m1 . . . m4 that are statically fixed to the base plate bp . the coils sp1 , sp2 are arranged , as illustrated in fig2 at outer sides on the carrier t with their axes parallel to the plane of the carrier t in the direction of deflection and the adjacently located permanent magnets m1 , m2 and m3 , m4 forming a respective pair exhibit the same magnetic poles on their oppositely located sides . in correspondence with fig2 the arrangement is built up symmetrically and the active manoeuvering means provided as coils sp1 , sp2 lead to a linear deflection when controlled in a similar sense in correspondence with fig2 b and to a twisting or to an angular deflection of the carrier t and of the objective lens ol when controlled in opposite senses in correspondence with fig2 c . by superimposing the control signals , both a linear deflection as well as a deflection through an angle are achieved . the symmetry of the resilient moulded parts thereby ensures that the deflection direction coincides with the direction of the deflecting force . the first coil pair is provided for the deflection in the radial direction x and through an angle in the plane formed by the radial direction x and the focusing direction z , and the second coil pair is provided for the deflection in the tangential direction y and through an angle in the plane formed by the tangential direction y and the focusing direction z . the actuator , which is formed here by an objective lens ol , is deflectable in three linear directions and in two angular directions with only five coils that are controllable independently of one another . using the resilient moulded parts f1 , f2 , the carrier t thus has at its disposal a mechanical guide and also it is deflectable in the desired directions . the compliant support by the resilient moulded parts f1 , f2 is effective against vibrations and prevents a contact of the actuator with a stationary part and the control voltages and currents required for the deflection have a simple relationship to a deflection which is to be carried out whereby an exceptional decoupling between individual adjustment forces is achieved , which forces on the other hand , can be superimposed so that the outlay required for the control is very small . the method given in de 40 28 703 , with which the regulating signals required for the perpendicular positioning of the actuator relative to the recording medium at are made available , can be used for the optimum positioning of the actuator or of the objective lens ol relative to the recording medium at . in particular for applications in which in normal operation , deviations with regard to the angle below which a light beam scans the recording medium at can be permitted , there is provided an embodiment of the invention sketched in fig4 . for the compliant support of the carrier t accommodating the objective lens ol , there are provided four resilient moulded parts f1 . . . f4 which are oppositely arranged , symmetrically of the objective lens ol , at the ends of the sides of the rectangular carrier t . the resilient moulded parts f1 . . . f4 are fashioned in step - like manner analogously to the previously described embodiment of the invention and connect the carrier t to the base plate bp in a corresponding manner . due to the four resilient moulded parts f1 . . . f4 which are arranged symmetrically , a more even , mechanically effective elasticity is achieved , in particular with respect to different deflections . four coils sp1 . . . sp4 are likewise arranged symmetrically of the optical axis of the objective lens ol , which coils are provided for the deflection of the objective lens ol in the focusing direction z as well as for the setting of angles in the planes which the radial direction x and the tangential direction y form with the focusing direction z . the guidance of the actuator to places on the recording medium at deviating from an actual position of the actuator is provided here exclusively by adjusting the tilt angle of the objective lens ol , which is effected by the coils sp1 . . . sp4 to which a respective permanent magnet is allocated . the deflection in the focusing direction z is effected by controlling in the same sense two of the four coils sp1 . . . sp4 , whilst an adjustment of the tilt angle is undertaken by controlling one of the coils sp1 . . . sp4 or by controlling in opposite senses two oppositely located ones of the coils sp1 . . . sp4 . however , combinations of resilient moulded parts f having manoeuvering means which deviate from this embodiment , are also realisable . the elasticity of the resilient moulded parts f is determined both by the properties of their materials as well as by their design . based upon this , examples for the design of the resilient moulded parts f are given in fig5 a . . . e which take into account in a special manner , the properties of the materials and also the desired damping characteristic as well as the manner of attachment to the carrier t and to the base plate bp . thus , in accordance with fig5 a , for a comparable modulus of elasticity , a greater elasticity is achieved by reducing the cross - section of the lower tread and reducing the length of the tread of a step - like resilient moulded part f and , in correspondence with fig5 b , a lower elasticity is achieved by reducing the number of steps . resilient moulded parts f are indicated in fig5 c . . . e in which the contact faces , at which the connection of the resilient moulded part f to the carrier t and the base plate bp is provided , run parallel to one another . the elasticity of the resilient moulded parts f due to the material is supplemented , in a constructional manner , by the constrictions or notches that are provided and the contact faces may be provided both perpendicular to and parallel to the planes of the carrier t or base plate bp . in further embodiments of the invention , resilient moulded parts f are advantageously combined with a parallel guidance of an actuator known in accordance with de 39 24 190 a1 or resilient moulded parts f are integrated into the parallel guide . in correspondence with fig6 the carrier t and the holding devices h1 , h2 in accordance with de 39 24 190 a1 forming the parallel guide are connected together via resilient moulded parts f1 , f2 . thereby , in cotrast with the guide having the parallel guidance which was originally intended to be as stable as possible , there is introduced an element which initially appears to be disadvantageous since its elasticity can lead to deviations . however , the elasticity of the resilient moulded part f has an advantageous effect in that manufacturing contingent tolerances or deviations , which are caused by the effects of high temperature , from the orientation of the actuator that was originally intended to be effected without any adjustment , can be subsequently corrected . the demands , and hence the associated costs , which have to be placed on the precision of the individual parts are reduced and moreover , by means of an appropriate regulation , a higher precision and flexibility can be achieved during the adjustment of the actuator relative to the recording medium at . a generally known coil arrangement , which is disposed opposite the permanent magnets , is used as the manoeuvering means . departing therefrom however , divided coils sp1a , sp1b are used , which coils are connected in series and provide for a control in the focusing direction z that is as linear as possible . two further coils sp2a , sp2b , which serve for the control in the radial direction x , are respectively arranged on the coils sp1a , sp1b . the joints , which are effective as hinges , of the holding devices forming the parallel guide ensure a linear movement of the actuator in the focusing direction z and in the radial direction x . a rotational movement in the plane including the tangential direction y and the focusing direction z or about the radial direction x is achieved by a difference in the manner of controlling the coils sp1a , sp1b whose series circuit exhibits a centre tap for this purpose . for a rotational movement in the plane formed by the radial direction x and the focusing direction z i . e . about the tangential direction y , the coils sp3a , sp3b are controlled differently . an adjusting device having a member that is to be exclusively electrically controlled , is produced which can be used for a once - only automatic matching for ensuring , in normal operation , a constant perpendicular positioning of the actuator relative to the recording medium at using constant control voltages corresponding to the matching process or in connection with a regulation . the resilient moulded parts f1 , f2 are , in correspondence with fig6 resilient rectangular parallelpiped blocks of synthetic material . advantageously however , in a further embodiment corresponding to fig7 they may also be formed by notches in the vicinity of the connections between the holding devices h1 , h2 and the carrier t . the arrangement consisting of the holding devices h1 , h2 , the resilient moulded parts f1 , f2 and the carrier t is then made , in correspondence with fig7 from a single piece of synthetic material . in a further embodiment of the invention in accordance with fig8 a resilient moulded part f , which amalgamates the previously mentioned holding devices h1 , h2 and the carrier t , is provided for the guidance of the objective lens ol . in contrast to the holding devices known in accordance with de 39 24 190 a1 in which mobility is exclusively desired in the joints formed by notches , there is provided , for the arrangement in correspondence with fig8 a material that also exhibits elasticity away from these notches which then makes it especially possible to tilt the objective lens o1 without additional notches in the vicinity of the connections between the holding devices h1 , h2 and the carrier t such as are provided in accordance with fig7 . only one resilient moulded part f , which is combined with a number of active manoeuvering means that corresponds to the intended deflections , is required as the compliant support for the objective lens ol . the embodiment corresponding to fig8 is , analogously to the embodiment corresponding to fig4 provided for a linear deflection in the focusing direction z and for rotational movements about the radial direction x and also the tangential direction y . four coils sp1 . . . sp4 are disposed symmetrically with respect to the objective lens ol as the manoeuvering means , of which , two respective coils sp1 , sp4 or sp2 , sp3 are effective on a magnetic core formed by permanent magnets m1 or m2 . tilting movements are likewise achieved by means of different controls on the coils and the deflection in the focusing direction z is achieved by controlling all four coils sp1 . . . sp4 . a circuit arrangement for controlling the actuator arrangement corresponding to fig8 is given in fig9 . it consists of amplifiers v1 . . . v9 , resistors r1 . . . r12 and the coils sp1 . . . sp4 forming the active manoeuvering means . for the adjustment of the actuator , regulating voltages derived by known methods from the scanning signal are used : uz for the control in the focusing direction z , uzy for rotational movements about the radial direction x and uzx for rotational movements about the tangential direction y . the regulating voltage uz is supplied equally to the four coils sp1 . . . sp4 via the non - inverting amplifier v1 and a respective series circuit consisting of two resistors r1 , r2 ; r3 , r4 ; r5 , r6 ; r7 , r8 with a respective non - inverting amplifier v6 , v7 , v8 , v9 . the regulating voltage uzy for the production of a rotational movement about the radial direction x is supplied to the connection points of the respective two resistors r1 , r2 ; r3 , r4 ; r5 , r6 ; r7 , r8 connected in series , corresponding respectively to one of the coil pairs sp2 , sp3 and sp1 , sp4 which are provided in pairs , via the non - inverting amplifier v2 or the inverting amplifier v3 . analogously , there are provided a non - inverting amplifier v4 and an inverting amplifier v5 which are connected to the regulating voltage uzx for the production of a rotational movement about the tangential direction y and which feed a signal corresponding to the regulating voltage uzx into the amplifiers v6 . . . v9 connected to the coils sp1 . . . sp4 via respective resistors r9 , r10 and r11 , r12 connected thereto . the non - inverting amplifier v4 thereby feeds the oppositely located coils sp1 and sp2 in the coil pairs sp1 , sp4 and sp2 , sp3 via the resistors r9 and r10 and also the non - inverting amplifiers v6 , v7 . the coils sp3 and sp4 are connected via the non - inverting amplifier v8 and resistor r11 or the non - inverting amplifier v9 and resistor r12 to the inverting amplifier v5 . if a linear deflection in the radial direction x is also wanted , further manoeuvering means can be provided so that a building block type of system is available which can be built up in accordance with the requirements . the actuator arrangement may , as described in the embodiments , receive a scanning head ak in the form of an objective lens ol in cd players , a scanning and / or recording head ak for re -
