Claims

[Claims for Utility Model Registration] A magnetic head is mounted on a head base that reciprocates in a direction substantially perpendicular to the running direction of the magnetic tape, and by reciprocating the magnetic head together with the head base, the magnetic head can be moved relative to the magnetic tape. In a tape recorder that makes contact with and separates from the magnetic tape, an intermediate head base that is movable within a predetermined range substantially along the direction of movement of the head base is attached to the head base, and the intermediate head base is placed so as to face the magnetic tape. The magnetic head is mounted on the intermediate head base, and when the magnetic head contacts the magnetic tape and the running direction of the magnetic tape is reversed, the magnetic head is mounted on the intermediate head base. A tape recorder further comprising a moving mechanism for moving the intermediate head base and temporarily separating the magnetic head from the magnetic tape.
