Abstract

The utility model provides a DVD-ROM disc encrypted by a cauterization technology, which comprises a disc body, a disc centre hole, a disc clamping disc, a disc information surface and a disc printing surface, a physical damage ring is provided on the disc information surface, and the disc information surface and the disc body have same center of the circle, the start radius of the physical damage ring is positioned at 24.5mm of the disc radius, and the width of the physical damage ring is 0.3mm-0.4mm. The DVD-ROM disc by cauterization technology can generate data read error while being copied of the prepared DVD-ROM disc, and the illegal copying can be effectively avoided.

Description

A kind of DVD-ROM CD that burns technology secrecy

Technical field

The utility model relates to a kind of DVD-ROM CD, especially a kind of DVD-ROM CD that burns technology secrecy.

Background technology

The piracy of DVD-ROM CD is relatively more rampant at present, has caused a large amount of loss of markets for many publishers and video display company, has also greatly invaded copyright owner's interests.Take precautions against one of pirate most important work of being concerned about most that has become each big publisher.How scientifically designing the anti-piracy technique of DVD-ROM, is the difficult point that faces at present.

Summary of the invention

The purpose of this utility model is to propose a kind of anti-piracy technique physically, in the information faces of CD one physical damnification annulus is set, and can prevent that the DVD CD is by illegal copies.The technical solution adopted in the utility model is:

A kind of DVD-ROM CD that burns technology secrecy, comprise CD body, cd center hole, CD clamp area, optical disc information face, CD printing surface, at the optical disc information face one physical damnification annulus is set, described physical damnification annulus and CD body concentric, the start radius of physical damnification annulus is positioned at the 24.5mm place of CD radius, and the width of physical damnification annulus is 0.3mm～0.4mm.

Principle of the present utility model is such,

Before making the DVD-ROM CD, generally need to make earlier stamper.Need to embed suitable anti-piracy technique at stamper.The DVD-ROM CD that utilizes stamper to suppress then also can possess the anti-piracy technique with the stamper unanimity.

Before making stamper, at first the source of parents data that the client is provided are carried out logical encrypt.Common way is: use imprinting software to set up the data of optical disk form of corresponding DVD-ROM earlier; Write encryption menu then in described data of optical disk form, the source of parents data that again client provided write in the described data of optical disk form, regeneration image file ISO; Subsequently described encryption menu, data directory are hidden; Carry out the imprinting of stamper at last.

Because encryption menu is positioned at the beginning zone of the program of stamper, be between CD radius 24.3mm～25mm at physical location on the DVD CD, after therefore this interval interior a part of continuum being burnt, just can prevent DVD CD illegal copies.Therefore when mother CD burning, after data carving is finished, also need to carry out burning of stamper, form one with the information faces at stamper and burn annulus.This burns the 24.5mm place that the annulus start radius is positioned at the stamper radius, and width is 0.3mm～0.4mm.

After stamper has been made, just can utilize stamper compacting DVD-ROM CD, all information in this process on the stamper will be transferred on the DVD-ROM CD, therefore burn annulus on the corresponding stamper, can form a circle physical damnification annulus at the DVD-ROM CD, the position of this physical damnification annulus and width all with stamper on the position of burning annulus identical with width.

Advantage of the present utility model: can make the DVD-ROM CD of making when copying, produce data read errors, can prevent bootlegging effectively.

Embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

At first make stamper:

Before making stamper, at first the source of parents data that the client is provided are carried out logical encrypt.Use Nero imprinting software to set up the data of optical disk form of corresponding DVD-ROM earlier; Write encryption menu then in described data of optical disk form, the source of parents data that again client provided write in the described data of optical disk form, regeneration image file ISO; Subsequently described encryption menu, data directory are hidden; Carry out the imprinting of stamper at last.

When mother CD burning, after data carving is finished, also need to carry out burning of stamper, form one with the information faces at stamper and burn annulus.This burns the 24.5mm place that the annulus start radius is positioned at the stamper radius, and width is 0.3mm～0.4mm.

After last stamper has been made, just can utilize stamper compacting DVD-ROM CD, therefore all information in this process on the stamper will be transferred on the DVD-ROM CD, burn annulus on the corresponding stamper, can form a circle physical damnification annulus 4 at the DVD-ROM CD.

The DVD-ROM CD that is pressed at last is as shown in Figure 1 and Figure 2:

A kind of DVD-ROM CD that burns technology secrecy, comprise CD body, cd center hole 1, CD clamp area 2, optical disc information face 3, CD printing surface 5, at optical disc information face 3 a physical damnification annulus 4 is set, described physical damnification annulus 4 and CD body concentric, the start radius of physical damnification annulus 4 is positioned at the 24.5mm place of CD radius, and the width of physical damnification annulus 4 is 0.3mm～0.4mm.

When using the whole dish of software such as Nero to copy this encryption DVD-ROM CD as the bootlegger, burnt regional continuous data read errors and caused copying failure owing to run into.

The zone of physical damnification annulus 4 does not surpass the encryption menu region (between CD radius 24.3mm～25mm) on the DVD-ROM CD, can not damage normal data.

Claims

1. DVD-ROM CD that burns technology secrecy, comprise CD body, cd center hole (1), CD clamp area (2), optical disc information face (3), CD printing surface (5), it is characterized in that: at optical disc information face (3) a physical damnification annulus (4) is set, described physical damnification annulus (4) and CD body concentric, the start radius of physical damnification annulus (4) is positioned at the 24.5mm place of CD radius, and the width of physical damnification annulus (4) is 0.3mm～0.4mm.
