Description

Color RW-CD and manufacture method thereof

The present invention relates to a kind of color RW-CD and manufacture method thereof, relate in particular to a kind of RW-CD and manufacture method thereof that high power speed burning ability has a specific color again that possess.

Along with the prosperity and the demand that adapts to the no paper epoch of science and technology, RW-CD is because have ability that stores great mass of data and the advantage with permanent preservation data, so RW-CD is widely used in the data of storage image, music or writing etc.Please refer to Fig. 1; generally speaking; RW-CD comprises four layer materials; ground floor is the substrate 1 that is formed with precasting groove (Pre-groove); the second layer is by the formed record layer 2 of organic dyestuff (Dye) (or claiming dye coating); the 3rd layer is that 3, the four layers in the formed reflection horizon of proof gold or fine silver is the formed protective seam 4 of resin.When the burning signal because record layer can absorb a burning CD-ROM drive laser beam, and produce heat energy, make by laser beam irradiation to the zone react, produce structural change and cause the reflectivity difference.When burning finishes when desiring to read data, read the principle of data as read-only optical disc sheet (CD-ROM), utilize the record district of laser beam irradiation on discs, the difference of the laser power that reflects is to be interpreted to digital data.

The used organic dyestuff system of record layer has at present: the blue dyestuff (Cyanine Dye) of cyanines, phthalocyanine dye (Phthalocyanine Dye) and azo metal complex (AZO-Metal Complex).Wherein, the blue dyestuff of cyanines is blue, and phthalocyanine dye is extremely light yellow green, and it is blue that azo metal complex then is.With the blue sheet of the water that is commonly called as is example, and the material that it is serves as the record layer with the blue dyestuff of cyanines is the material in reflection horizon with the fine silver, makes the outward appearance of this RW-CD present blue.In addition, the platinum embolium that is commonly called as is to be the material of record layer with the phthalocyanine dye, and fine silver is the material in reflection horizon, makes the outward appearance of this RW-CD present the platinum green.What deserves to be mentioned is, because the phthalocyanine dye permanence is high with respect to the blue dyestuff of cyanines, so the life-span of the RW-CD of the blue dyestuff of comparable cyanines of the life-span of the RW-CD of phthalocyanine dye is for long.The more important thing is that the RW-CD of phthalocyanine dye possesses the function of fast writing discs, therefore be particularly suitable for high power speed burning CD.Generally speaking, the RW-CD of the blue dyestuff of cyanines comes burning with twelvefold speed at most, and the RW-CD of phthalocyanine dye then can come burning with 16 times of speed more than the speed at least.

Yet, along with the demand and the burning CD-ROM drive development of technology of consumption market, also constantly release the more burning CD-ROM drive of high power speed on the market, as the burning CD-ROM drive of at present existing 16 times of speed.Ordinary consumer can be because of the difference of the color that RW-CD presented, and influences its purchase intention, therefore how to produce to have high multiple burning ability, has the RW-CD of specific color again, is an important problem in fact.

In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind ofly to have the ability of high power speed burning and have the color RW-CD and the manufacture method thereof of specific color.

For achieving the above object; the invention provides a kind of manufacture method of color RW-CD; this color RW-CD comprises that a substrate, is formed at record layer, on this substrate and is formed at a reflection horizon on this record layer and a protective seam that is formed on this reflection horizon.The manufacture method of this color RW-CD comprises: with a coloured coloring material for mixing in the dyestuff that the burning of high power speed is used, to form the record layer dyestuff with particular color (comprising colourless), the record layer dye-coating that again this is had particular color is on this substrate, to form this record layer, so that this color RW-CD presents a specific color.

The present invention also provides a kind of color RW-CD, and it comprises that a substrate, is formed at record layer, on this substrate and is formed at a reflection horizon on this record layer and a protective seam that is formed on this reflection horizon.Record layer is the record layer dyestuff with particular color (comprising colourless) that is mixed by the dyestuff that the fast burning of a coloured colorant and a high power is used, and coats on this substrate to form, so that this color RW-CD presents a specific color.

By color RW-CD of the present invention and manufacture method thereof, be the dyestuff that coloured colorant and the burning of high power speed are used to be mixed with formation have the particular color dyestuff of (comprising colourless), because the dyestuff that this high power speed burning is used has the ability of high power speed burning, so can produce ability with the burning of high power speed and color RW-CD with specific color.
