Abstract

The invention concerns a floppy disc drive unit in which all the movements are made automatically with the aid of two motors. Using a positioning motor positioning a magnetic head on various tracks of the floppy disc, the floppy disc is automatically drawn into the floppy disc drive unit and ejected therefrom. With the aid of a driving motor provided to drive the floppy disc, the floppy disc is clamped and unclamped and felt pressure pads are lowered and raised automatically.
