Embodiment Construction

[0046] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation methods, production methods, steps, The features and their functions are described in detail below, and the same components will be described with the same reference symbols.

[0047] As shown in FIG. 2 , the disc original plate production method includes the following steps: dry cleaning on a substrate (S10), coating a photoresist layer on the substrate (S30), laser engraving and developing the photoresist layer (S50), and forming a metal layer on the photoresist layer (S70). In this embodiment, the original disc is used to make a disc template (Disc Stamper) for the optical recording medium.

[0048] Please refer to FIG. 2 and FIG. 3 , in step S10 , a substrate 21 is dry-cleaned. In this embodiment, the material of the substrate...

Abstract

The method includes steps: carrying out dry type cleaning for base plate; coating a photoresistive layer on the base plate; laser etching and developing photoresistive layer, and forming a metal layer on the photoresistive layer. Dry type cleaning saves water resource, cleans contaminants adhered on base plate so as to be good for coating the photoresistive layer. Dry type cleaning does not cause surface of base plate to carry electric charges so as to reduce chance for adsorbing pollutant again. Moreover, the dry type cleaning makes surface of base plate become coarseness. Therefore, adhesion capability between base plate and photoresistive layer is raised.

Description

technical field [0001] The invention relates to a disc original production method, in particular to a disc original production method for preparing a disc template. 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, CD-ROM, and CD-ROM. DVD-ROM, DVD-R, DVD-RW, DVD+RW, and DVD-RW RAM) and so on. [0003] In the production process of optical recording media, the disc template (Disc Stamper) with grooves or holes 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 carry out Subsequent processes to produce large quantities ...
