ABSTRACT:
A magnetic disk drive capable of performing a head seek at high speed even when a track pitch of the recording track of the magnetic disk is narrowed. The structure eliminates incomplete erasure caused by a positioning error of a recording head and prevents side-fringe magnetic field from erasing a signal on an adjacent track in order to obtain a larger reproduction output.
