Abstract:
A system and method are disclosed to facilitate independent positioning of a plurality of heads relative to associated disk surfaces in a disk drive system. Circuitry is provided to route position data from at least one of the heads while concurrently reading data from or writing data to another head. The position data is employed to control the position of the heads, each of which may be independently positioned by an associated positioning motor. Servo wedges associated with each surface also may be offset from each other to facilitate acquiring position data from one or more heads while data is concurrently communicated relative another head.
