ABSTRACT:
In an apparatus for recording and/or reproducing signals on a flexible disc which is rotatably mounted in a jacket having an indicator for indicating the number of tracks on which the signals have already been recorded, a transducer records and/or reproduces the signals on a surface of the disc so as to form a plurality of circular tracks thereon. The transducer is subsequently moved in the radial direction of the disc to the next adjacent track. The apparatus is further provided with an indicator driving mechanism for driving the indicator of the jacket to shift the latter to a corresponding position as related to the number of the recorded tracks. The indicator driving mechanism is driven in synchronism with the movement of the transducer.
