Disk templet manufacturing method

Abstract

The invention discloses a disc stencil preparing method, which comprises the following steps: cleaning one base plate; applying one optical barrier layer on base plate; laser engraving and developing optical barrier layer; sputtering and plating one metal inlay on base plate and optical barrier layer; electroforming to thicken metal layer; forming one father stencil; separating optical barrier layer and father stencil; cleaning father stencil in dry-type.

Description

technical field [0001] The invention relates to a method for making a disk template, in particular to a method for making a disk template for preparing an optical storage medium. Background technique [0002] With the advent of the information and multimedia era, the storage density and capacity of the storage media required by electronic products are 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 )wait. [0003] In the production process of optical recording media, disc stampers with grooves or cavities are generally used together with injection molding machines to mass-produce optical recording media substrates with patterns corresponding to the disc stampers. [0004] Such as figure 1 As shown, the existing disk templat...

Problems solved by technology

If these pollutants are not removed, the disc template will be used in the injection molding process to produce the substrate of the optical recording medium, which will cause uneven surface of the substrate and affect the quality of the optical recording medium.
