ABSTRACT:
A disk clamping mechanism for disk recording and reproducing devices of the type in which when a disk cartridge with a disk enclosed therein is inserted into the device the disk clamping mechanism is actuated to clamp the raised groove guard formed around the rim of the disk so that when the cartridge is pulled out of the device the disk remains therein. The clamping mechanism includes a pair of clamping fingers with projections adapted for engagement with the groove guard when the forces pulling out the cartridge are transmitted to the disk. A linkage or a mechanism comprising a wedge and tapered surfaces is operatively connected to the clamping fingers in such a way that when a pulling force is exerted on the disk and the clamping fingers, the linkage or mechanism causes the clamping arms or fingers to move further toward each other, thus exerting a stronger clamping force on the disk.
