<p><P>PROBLEM TO BE SOLVED: To provide a disk stopper which can securely grip a disk and rotatably drive the disk with certainty, and can release the disk successfully even after clamping the disk for a long time in high temperature. <P>SOLUTION: A disk stopper is formed by stacking a grip layer 1 composed of thermoplastic elastomer having a high static friction property and an adhesive layer 3. The disk stopper is bonded to a turntable T to prevent displacement of the disk D. A release layer 2 composed of non-adhesive resin is scattered on a surface of the grip layer 1. The release layer 2 is buried in the grip layer 1 due to elasticity of the grip layer 1 so that a surface of the disk D comes in contact with the grip layer 1 to be gripped. When releasing the disk, the release layer 2 projects from the surface of the grip layer 1 by elastic return of the grip layer 1 so that the disk D is separated from the grip layer 1. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
