ABSTRACT:
A double-sided floppy disk driving apparatus having a clamping mechanism provided with a manually-operated lever for moving a clamper pressure plate down, thereby lowering a clamper and clamping a medium, and a mechanism interlinked with said clamping mechanism for moving read/write heads close to each other. The apparatus has a paddle plate having an arm at one end thereof and an opener at the other end thereof. The arm of the paddle plate is pushed down by the clamper pressure plate for pushing down said clamper in order to move said read/write heads close to each other. The apparatus further comprises a head mutual contact-prevention mechanism provided in the vicinity of said paddle plate. The mechanism has a member which is moved to a position under said paddle plate when a medium is not loaded, and which abuts against a loaded medium, is actuated thereupon, and is released from under said saddle plate.
