Description of the Invention (1) Field of Invention. The present invention relates to an optical disc and a method for manufacturing the same, and more specifically, T 'refers to a colored optical disc and a method for manufacturing method. BACKGROUND OF THE INVENTION Generally, optical discs on the market include compact discs (CDs), read-only optical discs (CD-ROMs), single nested optical discs (cd-R), and read-write optical discs (CD-RW). And digital video discs (dvD), which are mainly composed of a transparent substrate and a reflective layer. Recording optical discs such as CD-R also include a dye recording green layer; the production process can be briefly described as follows: first, it is produced by injection molding. Substrate 'Then apply a thin film of light absorbing material on the substrate, and then sputter the reflective layer. This is the basic manufacturing process of disc-related products. Depending on the product category, the materials used in the recording layer will also vary. . But as far as the substrate is concerned, the current users in the industry still mainly use transparent substrates. The reason is that the transparent substrate is obtained by injection molding of transparent and colorless plastic particles. Because it has no color, it is not easy to read the incident light with data. The emitted light interferes with the reading result. Read the data recorded on the optical disc, or record the desired data on the CD-R, and record it in the recording layer after the reading of the readout of the laser. The incident light emitted by the read / write head is recorded. The light needs to pass through the transparent substrate first. At present, the laser light used to read CD data is red light with a wavelength of about 780 nm, while those used to read DVD optical media have a wavelength of about 650 nm. Since the advent of optical discs, the industry has used plastic granules as the raw material for substrates. And because plastic granules are transparent and colorless, they are transparent and colorless. -4- This paper size applies to China's family standard (CNS) A4 specification (210X297). (Li) ------------ ^ ------ 1T ------ ^ (Please read the notes on the back before filling this page) 452790 A7 B7 V. Description of the invention (2 ) Substrates have always been known to the industry and have followed J. In recent years, in order to increase the diversity of optical disc products and simultaneously play the role of data, although the industry has tried to dye substrates with color know-how, it can successfully dye substrates. Zhiyan Luba is only black '. As for other colors, because the wavelength of the two rays of light incident from the reading hair out of the reading hair has a similar absorption wavelength, dry rolls will occur. The shortcoming of the accuracy of the whistle is how to successfully dye other colors than black on the transparent substrate, such as red, yellow and blue, etc., while avoiding interference with the laser light that hits the person and affects it. The problem of reading the correctness of recorded data becomes The main technical problems to be overcome in the manufacture of color substrates. The injection molding process of the conventional optical disc substrate can be summarized as follows: ⑴Clamping: After the mold is closed, the clamping force is strengthened. ⑵ Injection: The screw advances forward, and the plastic material in the molten state at the front end of the screw is injected into the cavity. (3) Holding pressure: The plastic material can obtain better reproduction effect in the mold cavity that keeps high pressure. (4) Cooling: ①In the early stage of cooling, 'the cutter will advance, and cut out the center hole of the disc " ②At the end of cooling, blow the mold first to make sure that the substrate is slightly separated from the mold mirror surface, and then blow the mold to the movable side. The gas' slightly separates the entire substrate from the stamper. (5) Mold opening: Air blowing is performed on both the fixed and movable sides of the mold to completely separate the substrate from the mold.

After sufficient mixing and cooling, the red substrate was opened to remove the red substrate. The red substrate was tested with an absorption spectrometer and it was found that the absorption wavelength was 509 nm, which was equal to the incident laser light of the compact disc drive. The wavelength (780nm) is not the same, even when compared to the wavelength (650 nm) of the incident laser light of the DVD player, so the effect of dyeing the substrate and avoiding interference with the incident laser light can be achieved = implementation Example 2 Take the manufacture of compact discs as an example.
