Magnetic tape unit
 A magnetic tape unit with a magnetic head for reading and writing data from and onto a magnetic tape. The magnetic tape is kept in constant contact with the magnetic head, and a reel motor travels the magnetic tape kept in contact with the magnetic head. Adhesion of the magnetic tape to the magnetic head is prevented by slowly driving the reel motor to travel the magnetic tape at a speed lower than a normal traveling speed for a read/write operation of the magnetic head, during a rest period when the read/write operation of the magnetic head is not performed.
