Embodiment Construction

[0043] Below with reference to relevant drawings, illustrate the preferred embodiment of the disk template manufacturing method according to the present invention

[0044] Example.

[0045] Such as figure 2 As shown, the disk template manufacturing method includes the following steps: cleaning a substrate (step S10), coating a photoresist layer on the substrate (step S30), laser engraving and developing the photoresist layer (step S50), sputtering A metal layer on the substrate and the photoresist layer (step S60), electroforming to thicken the metal layer to form a parent template (step S70), separating the photoresist layer and the parent template (step S80), and dry cleaning the parent template (step S90). In this embodiment, the disc template is mainly used to manufacture the substrate of the optical recording medium, and the disc template mainly includes a father stamper (Father Stamper) and a son stamper (Son Stamper). Of course, the mother stamper produced from the ...

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...
