Problems solved by technology

[0009] The purpose of the present invention is to overcome the deficiencies and defects of the prior art, and provide a template and a method for manufacturing an optical information storage medium, so as to solve the gap between the template and the spacer layer when the existing single-sided double-layer DVD-R disc strips the template. Then the problem of too strong force, and then solve the problem of low yield rate of the disc manufacturing process

Abstract

This invention relates to formwork used in the production of an optical storage medium. The formwork includes a base plate and a reformed layer, among which, the base plate has multiple pre-carved trenches and the reformed layer is set on the base plate. This invention also discloses a manufacture method for a light information storage medium.

Description

technical field [0001] The invention relates to a template and a method for manufacturing an optical information storage medium, in particular to a template with a modified layer and a method for manufacturing an optical information storage medium. Background technique [0002] With the advent of the information and multimedia age, the demand for storage density and capacity of storage media in electronic products is also increasing. Traditional storage media can be roughly divided into two categories, namely magnetic recording media and optical recording media. At present, the market is dominated by optical recording media, which include CD-ROM, CD-R, CD-RW, digital DVD-ROM, DVD-R, DVD-RW, DVD+RW, and DVD-RAM )etc. [0003] Facing the ever-increasing amount of video and audio information, increasing the data capacity of optical discs has always been the goal pursued by the industry. And because DVD has a larger data storage capacity than CD, it has occupied a certain pr...
