PURPOSE: An optical disk protection structure of optical disk player is provided to prevent crack generation when clamping previously by using a reinforced part which is placed at a clamping area composing a disk. CONSTITUTION: An adhesion layer(4) is formed at a central part of an optical disk. A recording layer(5,6) is formed at both surface based on the adhesion layer(4). A dielectric layer(7,8) is formed to protect the recording layer(5,6) at the external side of the recording layer(5,6). A reinforcement part to increase strength of a clamping area is placed at the clamping area of an optical disk. A reinforcement layer(100) is coated in a designated height as the reinforcement part. The reinforcement layer(100) uses the dielectric layer to be material same as the clamping area. |
