FABRICATION METHOD OF AN OPTICAL DISK, SPECIFICALLY RELATED TO REMOVING NON-UNIFORM THICKNESS DISTRIBUTION OF THE OPTICAL DISK

摘要

PURPOSE: A fabrication method of an optical disk is provided to continuously form an edge of a disk and an edge of a housing, while maintaining the disk in cleaner state than an existing proposed housing, thereby reducing a recording/reproducing error. CONSTITUTION: The first dielectric layer, a recording layer, the second dielectric layer, and a reflecting layer are sequentially formed on a transparent substrate of an optical disk. The optical disk is inserted into a housing having the same inner diameter as an external diameter of the optical disk to perform a spin-coating process. A protection layer is formed by hardening the housing by UV rays.
