Mould for manufacturing optical information storage medium and method for manufacturing optical information storage medium

Abstract

A die set for manufacturing light information storage medium includes a formwork and an isolation element, in which, a trench is formed on a surface of the formwork, a first punch and a containing part are formed at the middle of the formwork, the containing part is circled at the first punch and adjacent to the surface with the trench, the isolation element is in the containing part, the center of the isolation element has a second punch coaxial with the first punch, two recesses are formed on the side of the isolation element facing to the formwork. The die set for manufacturing light information storage medium is used of manufacturing the isolation layer between medium and trenches of the formwork become relatively the precut trench of the space layers.

Description

technical field [0001] The present invention relates to a mold for manufacturing optical information storage media and a method for manufacturing optical information storage media, in particular to a mold for manufacturing single-layer double-sided DVD-R and a method for manufacturing single-layer double-sided DVD-R. 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. One of the most important storage media currently on the market is optical information storage media, which includes CD-ROM, CD-R, and CD-RW. , read-only digital laser disc (DVD-ROM), rewritable digital laser disc (DVD-R), rewritable digital laser disc (DVD-RW, DVD+RW), and dynamic random memory digital laser Video disc (DVD-RAM) and so on. Among them, because DVD has a larger data storage capacity than CD, it has already occupied a certain proportion in the optical infor...

Problems solved by technology

[0006] However, since the stencil 24 and the spacer layer 13 will be tightly combined after being pressed together, when the stencil 24 is peeled off, the pre-grooves on the spacer layer 13 will be damaged due to improper force application, thereby destroying the integrity of the spacer layer 13 , and cause a bad film; for example, the known technology inserts the mechanical arm directly between the template 24 and the spacer layer 13, and this action is carried out in a destructive manner, that is, the direct insertion of the mechanical arm between the mold and the spacer layer will destroy the spacer Structure of layer 13
