Side-by-side read/write heads with rotary positioner

摘要

A disk drive (10) includes a head positioner (16) on which are mounted separate read and write heads (52 and 54) that are spaced apart in the direction radial of the disk axis. Headers (50) on a disk (12) in the disk drive (10) establish track pitches that vary with radial position in such a manner that the radial separation of the read and write heads (52, 54) is equal to an integral number of track spacings that is substantially independent of the positioner angle.
