Claim:
An apparatus for clamping both large and small disks, comprising: a base; a disk tray located inside said base, said disk tray having a latch on an upper part and a rack on a front end; an upper case located above said base and said disk tray, said upper case having two grooves and two sliding tracks; and two clamping mechanisms located between said upper case and said disk tray, each of said two clamping mechanisms further comprising a gripper structure and a slider, said gripper structure having a first gripper, a second gripper, a first belt-ring, a second belt-ring and a resilient element located between said first and second belt-rings, and said slider moving inside the sliding tracks and having a latch hole for receiving said latch of said disk tray; wherein said two clamping mechanisms clamp a disk between said gripper structure and said disk tray with a force exerted by said resilient element, said disk tray causes said two clamping mechanisms to move inward into said base, and when said first gripper reaches an end of the grooves, said first gripper rotates upwards to cause said second gripper to rotate upwards, said first and second grippers move away from the disk, and said resilient element stops exerting said force.
