an optical head apparatus for an optical disc player which stabilizes the servo action , enables high speed access , extends the drawing range of tracking servo action , and further enhances the servo stability . this is done by making the driving mechanism and movable parts for access common to those for tracking to reduce the weight , and moving the stand carrying the condenser lens and mirror in focusing , tracking and accessing in the direction of the optical axis to eliminate deviation of the optical path , and also fixing the tracking and access coils to the condenser lens .
