Problems solved by technology

But at the same time, due to its low production cost and convenient distribution, pirated CDs have seriously affected the normal development of the CD market.
In the prior art, the optical discs made according to the normal production process are simple in process and low in cost, without any anti-piracy measures, so it is easy to copy, leaving opportunities for piracy
In the market, there are also some encrypted discs. Due to the flaws in their own encryption methods or measures, they cannot effectively prevent copying and curb piracy, and further efforts are needed.

Embodiment Construction

[0029] The present invention will be further explained below in conjunction with the accompanying drawings.

[0030] As shown in the accompanying drawings, it is the technical process of the present invention. In the method for making an encrypted disc, on the encrypted data sheet, encryption software is used to encrypt the parent source data, and at the same time, an encryption ring is added during the mastering process; a holographic laser pattern is made on the supporting sheet, and then one-to-one bonding encryption Information sheets and pattern support sheets are sufficient. Specific steps are as follows:

[0031] (1) Parent-source data software encryption:

[0032] Open the burning software NERO, create a new disc according to the media form of the parent source; add different encryption ring files according to different media forms and content sizes, the encryption ring file is any file with a fixed size without the suffix name, the size is about 190 ~ 210M , other ...

Abstract

The invention discloses a method for manufacturing a holographic laser encryption DVD disc, which comprising mother matrix manufacture and disc manufacture, wherein the mother matrix manufacture comprises the following steps: encrypting maternal data software, manufacturing an encrypted mother matrix and a holographic laser mother matrix; and the disc manufacture comprises the following steps: taking the mother matrix containing an encryption ring as a data sheet template, taking the mother matrix containing a holographic laser pattern as a backing sheet template, respectively pressing the data sheet template and the backing sheet template through a sub-disc copy line and adhering the templates one to one into the DVD disc. The method for manufacturing an encryption disc is an encryption way by combining software and hardware, has smart design, various encryption effects and very excellent anti-pirate performance and can accord with different encryption demands. The invention has the advantages that the backing sheet is provided with the holographic laser pattern, and a printing layer is omitted, thereby enabling the structure of the DVD disc to be simpler; the pattern is not easyto fade and copy, thereby having better anti-fake function; and the data sheet is additionally provided with the encryption ring, thereby having elegant appearance.

Description

technical field [0001] The invention relates to a method for making a DVD disc, in particular to a method for making a holographic laser encrypted DVD disc. Background technique [0002] At present, with the rapid development of social economy, people's demand for information is increasing, which promotes the rapid development of the optical disc industry. But at the same time, due to its low production cost and convenient distribution, pirated CDs have seriously affected the normal development of the CD market. In the prior art, the optical discs produced according to the normal production process are simple in process, low in cost, and do not adopt any anti-piracy measures, so they are easy to copy, leaving opportunities for piracy. In the market, there are also some encrypted optical discs. Due to the defects in their own encryption methods or measures, they cannot effectively prevent being copied and curb piracy, and further efforts are needed. Contents of the inventi...
