Abstract
Under existence of an impact and a vibration, a throughput and a reliability of a recording and reproducing operation in a magnetic disc apparatus are reduced. Accordingly, a mechanism for fixing a coarse moving actuator at an optional position is provided, at a time of following to a track, a motion of the coarse moving actuator is restricted and a positioning is performed by a fine moving actuator. Even when a vibration and an impact is applied from an external portion during the track following operation, it is possible to prevent the head position from being shifted and it is possible to perform a recording and reproducing operation. Further, it is possible to prevent adjacent data from being erroneously broken.
