ABSTRACT:
A disc transfer device for the manipulation of hard discs without damage to the recording surfaces thereof. The device is manually operated and consists of a U-shaped handle adapted for fitting over a disc storage spindle. The handle includes two grippers made of a rigid and smooth yet soft material which will not damage the disc surfaces. One gripper is fixedly attached to one end of the handle, and the other gripper is attached to a pivotable arm affixed to the other end of the handle. A lever attached to the movable arm allows for moving the arm outwards to enable a disc to fit between the grippers. A spring biases the arm in the normally closed position.
