an embodiment of the present invention implements some or all major servo subfunctions for a storage device in integrated servo fields comprising sequences of encoded bits having selected mathematical properties . the integrated servo field is composed of a number of encoded sequences , which are members of a selected sequence set that is constrained to preferably provide some or all of the following functions : the servo track mark , the position error signal and location information such as the track - id . the juxtaposition of sequences in the servo wedges is additionally constrained to increase the detectability of the contribution of adjacent sequences in the read signal . the integrated servo fields can provide a position error signal in relation to the center of a data track through the amplitude of the signal read for adjacent sequences .
