ABSTRACT:
A floppy disc recording and/or reproducing apparatus includes a driving shaft for rotationally driving a floppy disc, a cam body having a cam part, and a driving mechanism for rotating the driving shaft and the cam body independently of each other. A pair of guide parts are arranged on a single imaginary line and disposed on opposite sides of the driving shaft. A carriage has a head for recording and/or reproducing signals on and/or from the floppy disc which is rotated by the driving shaft. A pair of guided elements are located on the carriage, for linearly moving the carriage under guidance of the pair of guide parts. One of the pair of guided elements makes contact with the cam part of the cam body and is displaced as the cam body rotates, so as to move the carriage continuously.
