PURPOSE: A disk is provided to maintain the vibration-reduced effect using bismuth(Bi2O3) layer and a heat radiation layer. CONSTITUTION: The disk for recording data includes; a recording layer formed on the substrate; a vibration-reducing layer formed on the recording layer for reducing vibrations generated during high speed rotation movement of the disk; a heat radiation layer formed on the vibration-reducing layer for radiating heat generated from the vibration-reducing layer. The disk having the heat radiation layer can prevent shifting the shape of the disk so it is possible to be adapted for movement with high rotation speed. |
