ABSTRACT:
Magnetic tape recording and/or reproducing apparatus in which a head base is movable relative to a chassis between an inactive position in which heads mounted on the base are spaced from a tape contained, for example, in a cassette, and an active position in which at least one of the heads is engageable with the tape for recording or reproducing signals thereon. A first mode selecting device can be moved from a rest position to an operative position for moving the head base to its active position and for establishing the tape drive conditions required for reproducing and recording operations. A second mode selecting device can be moved from a rest position to an operative position for selecting the recording mode of the apparatus, for example, for changing over a switch from a condition for the reproducing mode to a condition for the recording mode and for permitting engagement with the tape of an erasing head on the head base. An interconnecting member responds to the transfer of the second mode selecting device to its operative position to move the first mode selecting device to its operative position. Accordingly, the recording mode of the apparatus can be established by moving only the second mode selecting device at a time when the first mode selecting device is in either its rest or operative position.
