MR HEAD DIFFERENTIAL MICRO-JOG

摘要

The present invention discloses a head positioning system (26) for accurately positioning a read/write head (24) along a selected track (22) of a rotating magnetic disk (20). In one aspect, servo information (64, 68) is embedded along the track (22) with the centerline (72) of the servo information (64, 68) offset a radial distance (88) from the centerline (56) of data stored or written along the track. The head positioning system (26) micro-jogs the read/write head (24) a first (84) and a second (88) radial distance from the centerline of servo information for a read operation (80) and a write operation (76).
