Description

200527411

(1), [Technical Field to Which the Invention belongs] The present invention relates to an optical recording medium, a compact disk (Compact Disk, CD), and an office of Shi Litu about a well including a Versatile Disk (DVD), etc. (2). [Previous technology] As far as the read-only optical disc structure is concerned, the lift plate 11 is made of a transparent material, such as polycarbonate ° 1, 基 ΓΓ ° Γ; ΐ; Γθΐ6, iV, 11 " ^ ^ ^ ^ ^

Formed in the United States fnT using Meng 1 as a material '#IJ uses the coating technology to form the reflective layer 1: on the substrate 1 1; the protective layer 13 is to form the protective layer 13 on the reflective layer 12, and the protective layer 13 is used to protect The "disc" is not man-made or damaged by foreign objects, which can increase the life of the disc. The data of this bubble read-only disc is formed simultaneously by the substrate during injection molding. The data of this read-only disc can only be read by the user and cannot be modified. The thickness of the disc is about 1.2 mm (nun). About 120 mm in diameter (120 mm

). The internal structure of another read-only digital video disc (DVD_ROM) is similar to that in Figure 1. The thickness of this digital video disc is reduced to 0.6 mm, and two 0.6 mm thick digital video discs are grid-connected and back-to-back glued to 1 Digital video disc with 2mm thickness. In addition, as shown in FIG. 2, using a coating technology, a recording layer 14 is plated between the substrate 11 and the reflective layer 12. The material of the recording layer 14 is an organic dye (Dye), and the recording layer 14 absorbs lightning. It emits light and converts it into thermal energy, so the local area where the recording layer 14 is exposed to laser light will generate local high temperature, which will cause organic dyeing.

Page 5 200527411 V. Description of the invention (2) The material is softened and deformed to form pits, and the pits are used to store the data. Since the organic dye of Lu Jilu layer 14 is not reversible in heat, the recording optical disc Data can be recorded only once. The number of structural layers, structural materials and manufacturing techniques of the various optical discs described above depend on the characteristics and design specifications of the various optical discs. The internal structure of another rewritable optical disc or rewritable digital video optical disc is similar to that shown in Figure 2. The recording layer is changed to a film with a thickness of 2000 to 5000 angstroms. The material is mostly silver. 'The crystalline layer of Shixi or Hoof. This material can show crystalline and non-crystalline state. It is interchanged between these two states by laser light'. These two states also present a flat and concave shape on the disc. The effect 'so you can achieve the purpose of repeatedly writing data. The principle of storing data on a disc is represented in binary by sound, image, and text, that is, it is composed of a series of |, 1 ”and“ 〇 ”. As shown in Figure 3, the disc is the substrate U in order from bottom to top. The reflective layer 12 and the protective layer 13 store the data on the disc by transforming a series of "1," and "0" into a series of recessed holes 15 and platforms 16 arranged in a circular track. The optical disc reading method uses laser light 2 to read the data of the optical disc. For example, when the laser light 2 is projected on the cavity 丨 5 from the direction of the substrate 11, the metalized cavity 丨 5 is like a mirror. 'Therefore, the laser light 2 will be reflected back. Since the depth of the cavity 15 is a quarter of the wavelength of the laser light 2, the light reflected from the cavity 15 and the light reflected from the platform 16 are both. The optical path difference is exactly half a wavelength. According to the principle of light interference, the two lights interfere with each other. In fact, there is no reflected light, that is, a signal of π 1π is generated. Conversely, when both lights are reflected from the cavity 1 5 Back, or reflected from the platform 16, there will be no interference phase

200527411

5. Description of the invention (3) When the signal is canceled, the reflected light will generate a signal of "0". Due to the advent of the multimedia age, today's films or animations are collectively referred to as optical discs and digital video and optical storage using optical discs and even digital video music, and the use of optical discs (below; coupled with the large storage capacity, makes multimedia data itself thin and light to use in large quantities to store Multi-media data is created by materials and materials, and it is required. Inch fly knows the body to meet the needs of multimedia. In addition, due to the popularity of burners and burning software, you can use the burning equipment to make your own copy. The data needed for the 1f times of Ding Table to blank light #Used: Μ 古. With time and time accumulated, more and more discs for the industry or life, in the future to find the desired disc, It is necessary to read the contents one by one with an optical disc drive, so that it can be distinguished and known, and it takes a lot of time and inconvenience in official management and use. Therefore, how to provide an optical recording medium that can solve the above-mentioned shortcomings for industry and users Convenient management and identification, which is eagerly awaited by all circles. (3) [Summary of the invention] In view of the above problems, the object of the present invention is to provide an additional An optical recording medium storing data. The reason is that, in order to achieve the above object, an optical recording medium according to the present invention includes a substrate, a reflective layer, and a protective layer. In the present invention, the substrate has a first surface, a Second surface and one side, second surface
