Abstract

The utility model provides a disc plate, wherein a protection layer is equipped on an information record face of the disc plate, the protection layer is a clear and transparent film, and the protection layer should better be composed of plural layers of stuck transparent films. The utility model adds a film protection layer on the disc plate information record face which is thin, high transparent and clear, and won't affect the normal operation and disc reading of the disc plate, the protection layer can be torn off from outer to inner for a plurality of times, thereby when the outmost of the disc plate is dirty or abraded relatively seriously which affects the normal disc reading of the device, the outmost protection layer can be torn off, now the disc plate recovers to the high degree clearance and smoothing the same as just buying, then the protection layer can be torn off for a plurality of times, when the protection layer is torn off, new plural layers of protection layers can be stuck again, which greatly prolongs the using life of the disc plate, users needn't worry about a series of performances of disc fetching and putting, and the economic lost brought by the damage of the disc plate to users are avoided.

Description

A kind of CD-RW discsCD-RW

Technical field

The utility model relates to CD-RW discsCD-RW, i.e. CD.

Background technology

Along with the raising of people's living standard and abundant, increasing household electrical appliance as CD-audio player, VCD video disc player, the mechanical, electrical brain of DVD digital video disk or the like, have all spread to huge numbers of families, and almost everyone also has the CD-RW discsCD-RW of many rich contents.

Existing compact disk structure as shown in Figure 1; the substrate that the A layer is made for highly Clear ﹠ Transparent plastics or organic glass; constitute the body layer of CD-RW discsCD-RW; the top of A layer then is to have constituted B layer (being generally serigraphy) by Information Level, aluminium matter reflection protection film, protective paint; people by the B layer as can be known this CD deposited the content of carrying, then store the digital information content of imprinting on CD-RW discsCD-RW on the bottom surface C of A layer.These CD-RW discsCD-RW all are to read information with laser beam, and the laser pick-up head does not contact with CD-RW discsCD-RW, do not have mechanical wear, so from the life-span of CD-RW discsCD-RW is permanent in a certain respect.

But manipulate in the process in actual frequent, but often make the C face of laser disc face suffer in various degree dirty and wearing and tearing, gently then make us need frequent wiped clean, and allow machine read dish to have some setbacks, make mistakes, influenced our amusement and recreation and work, heavy then CD-RW discsCD-RW can not be used, scrap fully, computer software CD particularly, a lot of all is that dozens of yuan, hundreds of unit buy, and can cause economic loss in various degree undoubtedly, has particularly also probably delayed important process.

Summary of the invention

At the existing problem of above-mentioned existing CD-RW discsCD-RW, the utility model provides a kind of CD-RW discsCD-RW that is provided with protective seam at the information burning face of CD-RW discsCD-RW.

Technical solution adopted in the utility model is: a kind of CD-RW discsCD-RW, it is characterized in that on the information burning face of CD-RW discsCD-RW, being provided with a protective seam, and this protective seam is Clear ﹠ Transparent film.

Said protective seam preferably is made of peelable multi-layer transparent film bonding.

Since the utility model CD-RW discsCD-RW information burning thinfilm protective coating that face has additional approach and highly transparent clear; can not have influence on the normal operation of CD-RW discsCD-RW and read dish; and this layer protective seam can also repeatedly be taken off from outside to inside layer by layer; like this when the outermost layer of CD-RW discsCD-RW because of dirty or wearing and tearing are more serious; when having influence on machine normal read dish; just can take the outermost layer diaphragm off; height when this moment, CD-RW discsCD-RW was recovered again just to have bought is clear smooth; so; but repeated multiple times is taken diaphragm off; when all being thrown off, diaphragm also can stick new multilayer resist again; prolonged the serviceable life of CD-RW discsCD-RW greatly; need not the user worries to do with falling courage and gets dish; a series of operations such as sale at reduced prices, and can avoid because CD-RW discsCD-RW is damaged and brings economic loss to the user.

This shows that design proposal of the present utility model is also brought following some beneficial effect undoubtedly.

One, technology is simple, and cost is humble, is easy to realize producing and promoting.

Two, on the market and user's existing old CD-RW discsCD-RW of staying at home, also can stick this multilayer resist voluntarily, can realize former CD-RW discsCD-RW protection.

Three, CD-RW discsCD-RW production firm directly makes up multilayer resist when producing new CD-RW discsCD-RW, makes the CD-RW discsCD-RW that has protective seam, further facilitates the user.

Embodiment

See also shown in Figure 2ly, the utility model CD-RW discsCD-RW is that the one deck that is sticked on the imprinting face C of existing CD-RW discsCD-RW main body basalis A pastes knot protective seam D together by the multi-layer transparent film, comes imprinting face C is effectively protected with this protective seam D.

Claims (2)

1, a kind of CD-RW discsCD-RW is characterized in that being provided with a protective seam on the information burning face of CD-RW discsCD-RW, and this protective seam is Clear ﹠ Transparent film.

2, CD-RW discsCD-RW according to claim 1 is characterized in that said protective seam is to be made of peelable multi-layer transparent film bonding.
