Abstract

An optical disk comprises a transparent substrate, a recording layer, and a protective layer, wherein the recording layer is adhered on the transparent substrate, the recording layer comprises a reflective layer, a transparent layer is adhered on the recording layer, and the protective layer is adhered on the transparent layer. The transparent substrate has a thickness within 0.5-0.9mm, and the protective layer has a thickness within 0.3-0.5mm. The utility model utilizes larger thickness space to protect the data layer of the disk while making adhered non-data protective layer effectively be used for commercial advertisement printing and other techniques for anti-counterfeit purpose.

Description

A kind of CD-RW discsCD-RW

The utility model relates to a kind of CD-RW discsCD-RW.

CD-RW discsCD-RW is the same with disk to be a kind of data storage medium that generally uses at present.CD-RW discsCD-RW is owing to consider the compatible problem of thickness and CD-ROM device; its integral thickness must remain on 1.2 millimeter; and the thickness of the transparency carrier of traditional CD-RW discsCD-RW is in 1.0 millimeter; the thickness of the overwhelming majority that accounted for; so the protection to the data logging layer can only realize with very thin hyaline layer; so very easily because of carry collision when taking, scratch makes the CD-RW discsCD-RW damage, this is that short maximum of CD-RW discsCD-RW life-span must not factor.In addition, because it is big that the reproduction speed of CD-RW discsCD-RW reaches circulation soon, so the non-data face of CD-RW discsCD-RW often has commercial advertisement and product mark, be used to strengthen vision and prevent counterfeit: but traditional way is the hyaline layer that in the mode of printing figure directly is printed on CD-RW discsCD-RW at non-data face with printing ink, or on the protective seam of CD-RW discsCD-RW, stick the paster that one deck has been brushed, reach commercial object with this; Therefore this method can't prevent and the CD-RW discsCD-RW thickness that produces is bonding, causes CD-RW discsCD-RW and CD-ROM device incompatible, the problem of fluctuation of service occurs.

The purpose of this utility model is to provide a kind of CD-RW discsCD-RW, makes the non-data mask of CD-RW discsCD-RW that the top layer of three-dimensional dynamic effect is arranged under the situation of not bonding CD-RW discsCD-RW thickness, and the recording layer that reaches CD-RW discsCD-RW carries out excellent protection.

For achieving the above object, the utility model has been adopted following technical scheme:

A kind of CD-RW discsCD-RW; comprise transparency carrier, recording layer, protective seam; wherein recording layer is bonded on the transparency carrier; comprise a reflection horizon in the recording layer; hyaline layer is bonded on the recording layer; protective seam is bonded on the hyaline layer, and the thickness of described transparency carrier is between 0.5～0.9 millimeter, and the thickness of protective seam is between 0.3～0.5 millimeter.CD-RW discsCD-RW is being placed recording layer between the thicker transparency carrier and protective seam under the situation that does not change general thickness; avoided collision, scratch and made the problem of CD-RW discsCD-RW damage; improved the serviceable life of CD-RW discsCD-RW, and made CD-RW discsCD-RW and the CD-ROM device can be compatible.While is compared with traditional CD-RW discsCD-RW and has lacked the layer of transparent layer, makes available space bigger.

Above-mentioned CD-RW discsCD-RW, described protective seam are the three-dimensional pasting board with three-dimensional dynamic effect.Make the commercial advertisement of CD-RW discsCD-RW like this and prevent that counterfeit effect is more feasible.So-called three-dimensional pasting board is meant and can produces three-dimensional dynamic pasting board when stirring.

Above-mentioned CD-RW discsCD-RW is characterized in that a bonding hyaline layer between described recording layer, the protective seam, is consistent with traditional CD-RW discsCD-RW structure on technology like this.

The utility model will be further described below in conjunction with accompanying drawing and embodiment:

Fig. 1 is traditional CD-RW discsCD-RW structural representation;

Fig. 2 is the utility model embodiment 1 structural representation;

Fig. 3 is the structural representation of the utility model embodiment 2.

With reference to accompanying drawing, number in the figure and parts are: protective seam 1, hyaline layer 2, reflection horizon 3, data Layer 4, transparency carrier 5, protective seam 6.

Embodiment 1:

With reference to accompanying drawing 2, be in the present embodiment under the situation that does not change CD-RW discsCD-RW structure and thickness, the thickness of transparency carrier 5 is located between 0.5～0.9mm, the thickness of protective seam is located between 0.3～0.5mm, play the effect of protection CD-RW discsCD-RW data Layer.

Embodiment 2:

With reference to accompanying drawing 3, present embodiment directly is bonded in protective seam on the data Layer as different from Example 1, and the thickness of transparency carrier 5 is located between 0.5～0.9mm, and the thickness of protective seam is located between 0.3～0.5mm.

Embodiment 3:

Present embodiment substitutes its described protective layer used three-dimensional pasting board with three-dimensional dynamic effect as different from Example 1.

Embodiment 4:

Present embodiment substitutes its described protective layer used three-dimensional pasting board with three-dimensional dynamic effect as different from Example 2.

Claims
