Abstract
A magnetic tape unit includes a magnetic tape provided with a plurality of tracks, a magnetic head for writing or reading data from the tape, a position determiner for monitoring the relative position between the tape and the head, and a position compensator for adjusting this relative position. The monitoring by the position determiner is performed based on signals read out from the servo control tracks of the tape. The position compensator keeps the magnetic head and tape in proper positional relation based on the results of the monitoring by the position determiner.
