ABSTRACT:
A recording and/or reproducing apparatus using a disc-shaped flexible record-bearing medium such as a disc-shaped flexible magnetic sheet, which includes a loading device for placing the medium at a predetermined position for signal recording and/or reproduction, a recording and/or reproducing head arranged to confront the medium when the medium is placed at the predetermined position, a rotation mechanism for rotating the medium relative to the head, a stop member for stopping the rotation of the medium by the rotation mechanism, and a control system responsive to the stop member for causing the loading device to retract the medium from the predetermined position, whereby the medium is prevented from being deformed by the head in a condition in which the medium is not being rotated by the rotation mechanism.
