In order to meet the optical storage system's need for higher density, higher capacity, higher communication speed and integration, a novel integration scheme is conceived. It has a key part called claw-type clamp. The clamp uses three flexible hinges as elastic parts to unfailingly clamp and positioning the disc without any clearance and abrasion. The theoretical analysis and computation show that the clamp meets the requirements of disc positioning and clamping. Working smoothly and evenly with 5000 r/min rotary speed, the experimental prototype can be used for optical storage.
