ABSTRACT:
A servosystem for controlling position of a magnetic head relative to a magnetic storage disk in a disk drive includes first and second feedback loops which provide head position error signals. The first feedback loop includes a head position circuit that processes different recorded Gray coded binary expressions that identify the data tracks on the disk during a track seek mode. The second feedback loop includes a head position circuit which, during the seek and track following modes, processes recorded quadrature servo signals that are interleaved with the data tracks.
