Embodiment Construction

[0059] The template and the manufacturing method of the optical information storage medium according to the preferred embodiment of the present invention will be described below with reference to the relevant drawings.

[0060]First, please refer to FIG. 4 to FIG. 7 to illustrate the manufacturing method of the optical information storage medium according to the preferred embodiment of the present invention.

[0061] In this embodiment, the template is used in a photopolymerization process (Photo-Polymerization Process, 2P Process) to manufacture an optical information storage medium. The optical information storage medium is a writable digital laser disc (DVD-R), and in this embodiment, a single-sided double-layer DVD-R formed by a 2P process is used to illustrate the manufacturing method of the optical information storage medium of the present invention the preferred embodiment.

[0062] As shown in FIG. 4, in this embodiment, the manufacturing method of the optical informa...

Abstract

This invention relates to formwork for manufacturing a light information 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 manufacturing 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...
