Abstract
The utility model discloses an encrypted DVD master plate which comprises a DVD master plate body, wherein an encrypting ring is arranged on the DVD master plate body. The encrypted DVD master plate has smart design, convenient making, good encryption effect and strong anti-piracy performance, and simultaneously has attractive appearance.
Description
Technical field
The utility model relates to a kind of DVD CD, relates in particular to a kind of encryption DVD mother matrix.
Background technology
At present, the DVD CD is more and more general, owing to the anti-pirate work of DVD CD is not but caught up with, so in the DVD CD that now circulates on market, some is pirate DVD CD.At the pirate situation of DVD CD, the also appearance of a small amount of encryption DVD disc on the market is but often because the defective of encryption method self or the price of encryption DVD disc costliness make the DVD CD-enciphering do not accepted extensively by users.
The utility model content
Goal of the invention: at the deficiencies in the prior art, the purpose of this utility model provides a kind of encryption DVD mother matrix, to realize the effective encryption to the DVD mother matrix, guarantees that simultaneously the DVD CD that produces with this mother matrix has encryption.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is:
A kind of encryption DVD mother matrix comprises that DVD mother matrix body is provided with encryption ring on described DVD mother matrix body.
The radius of described encryption ring is 24.25～24.75mm.Be the laser-induced thermal etching ring.
Described DVD mother matrix body is the mother matrix body of making of metallic nickel.
Encryption DVD mother matrix of the present utility model, in the mastering process, the DVD mother matrix that metallic nickel is made carries out encryption, and by at the DVD mother matrix laser-induced thermal etching ring being set, i.e. encryption ring reaches the purpose of encryption.This encryption ring is 24.25～24.75mm, and operated by rotary motion, can suitably increase and decrease according to the encrypt file size in the reference position of information, the mother matrix of making like this and all have cipher round results preferably by the DVD CD that mastering goes out.
Beneficial effect: encryption DVD mother matrix of the present utility model, design ingeniously, easy to make, cipher round results is good, has very strong anti-pirate performance, simultaneously good looking appearance.
Description of drawings
Fig. 1 is the vertical view of encryption DVD mother matrix of the present utility model.
Fig. 2 is the cut-open view of encryption DVD mother matrix of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further explained.
As depicted in figs. 1 and 2, be encryption DVD mother matrix of the present utility model.This encryption DVD mother matrix comprises the DVD mother matrix body of producing with metallic nickel 1, produces the laser-induced thermal etching ring at DVD mother matrix body 1 by the laser-induced thermal etching method, is encryption ring 2.The radius of encryption ring 2 is 24.25～24.75mm, and imprinting within it is useful on the file of encryption, thereby reaches the encryption purpose, so according to the actual size of encrypt file, the radius of encryption ring slightly increases and decreases.
