A sampled data read/write head positioning system for a disk drive having a sector servo overcomes the low bandwidth constraints of feedback position samplers. The system includes controlled acceleration and controlled deceleration of the read/write heads while seeking a track. In order to avoid missing track addresses, the sectors on each disk surface are staggered (offset) along each track from the corresponding sectors on the other disk surfaces, and each read/write head is used to find a particular track by sequentially switching the read/write heads while seeking.
