ABSTRACT:
A magnetic recording and/or playback apparatus for use with a tape cassette, in which a magnetic tape is accommodated, includes a magnetic head, a switching mechanism and a head moving mechanism. The magnetic head is movable between a recording and/or playback position where the magnetic head contacts the magnetic tape in the tape cassette to record and/or play back information signals on and/or from the magnetic tape and a position where the magnetic head is spaced from the magnetic tape in the tape cassette. The switching mechanism switches over the running direction of the magnetic tape between forward direction and reverse direction. The head moving mechanism moves the magnetic head between the recording and/or playback position and the spaced position. The head moving mechanism includes a pair of holding portions for holding the magnetic head in the recording and/or playback position. The pair of holding portions hold the magnetic head such that when the magnetic tape is run in the forward direction by the switching mechanism, one of the pair of holding portions holds the magnetic head in the recording and/or playback position, and when the magnetic tape is run in the reverse direction by the switching mechanism, the other of the pair of holding portions holds the magnetic head in the recording and/or playback position.
