Abstract

The invention relates to a method for producing the former plate of disc, which comprises: providing a heat source at the center of base plate; coating one light resistance layer above the base plate; laser etching and developing the light resistance layer; forming one metallic layer on the light resistance layer. The invention improves the light resistance coating technique to make it thin at center and thick at the edge; then the light resistance layer will form deep groove at the edge, to improve its quality.

Description

technical field [0001] The invention relates to a method for making a template, in particular to a method for making an original disc. Background technique [0002] In the production process of optical recording media, the disc template (Disc Stamper) with grooves or pits is generally used, and the method of injection molding is used to make a substrate with a corresponding pattern with the disc template, and then the Subsequent processes to produce large quantities of optical recording media. [0003] In order to obtain the disc template, you need to make a disc master (Disc Master). [0004] Please refer to figure 1 As shown, the conventional disc master 3 generally includes a glass substrate 31 ; a photoresist layer 32 coated on the glass substrate 31 ; and a metal layer 33 disposed on the photoresist layer 32 . The manufacturing method of the disc original plate 3 includes: wet cleaning a glass substrate 31, coating a photoresist layer 32 on the glass substrate 31, la...
