Invention Description (1) Technical Background [Technical Field] The present invention is about an optical record that records data in the form of thermal data by means of lasers and the like The optical recording material used in the media, and the optical recording medium using the material, more specifically, it is about a kind of high-performance Optical recording materials for density optical recording and reproduction: optical recording materials used, and optical recording media using the materials. [Relevant technical description] Generally, optical recording media has the characteristics that the recording medium will not wear out and deteriorate because the read-write head is not in contact with the medium, especially the data is made of optical data with thermal data. The media has advantages such as no need to borrow darkroom imaging processing, so it is being actively developed. This optical recording medium is an object that uses recording light as a form of heat. For example, a thin recording layer is provided on the substrate, and by forming optically detectable pits, data can be recorded at high density. Come down. Writing data into the recording medium is performed by scanning a laser beam on the surface of the recording layer to form a pit on the recording layer which absorbs the energy of the irradiated laser. The data recorded on this recording medium can be detected by optically reading the pits formed. As the above-mentioned recording medium, for example, it is a reproducible optical recording medium (CD_R) that corresponds to the specifications of optical discs (c㈣p⑽ D1SC, CD) and can be written by a near-infrared semiconductor laser with a wavelength of 77-83 nm, With the shorter wavelength of 620 ~ 690 nanometers near red semiconductor lasers to make the beam spot smaller, mention it! hll-I ---- 0 ^ ---- l · ---- Order -------- (Please read the notes on the back before filling this page) -4 5463〇〇A7 V. Invention Note (2 Printed by the Consumer Cooperatives of the Ministry of Economic Affairs and the Bureau of Intellectual Property of the People's Republic of China, and then using data compression technology, etc .: Recordable media such as digital optical recording media (ie, digital multi-function discs, DVDs): Write-back or record of green light recording media (dvd_r), etc .; For = media & recording layer, so far the main plugs have been used :: temple metal film, tellurium oxide film, succinic film or chalcogenide amorphous shell glass Inorganic optical recording materials such as films. = The material film is formed by the coating method. It is necessary to form the film by spraying or ... But its operation is complicated, and the above-mentioned blood organic matter is used. The shortcomings of high laser light reflectivity, high heat transfer rate, and low laser light utilization rate. Therefore, it is proposed to use an optical recording material that uses organic lasers to form pits by using semiconductor lasers and uses physical pigments as the main material. This is the method of recording layer. This temple pigment can use azo pigment, phthalocyanine pigment or cyanine Among them, indolinoline, oxazole-based, pyrimidine-based "cyanide pigments such as azole-based, quinoid-based, and selenazole-based cations and various anionic salts are formed by a flower = series pigments, which are preferred due to their high sensitivity Among them, it is called Budolin + Duohuatongbasu because it has a sensitivity of Tenan, so it is better. However, when the above organic compound pigments are used in optical recording materials, they have M formation characteristics and pit control when used alone. Insufficient light and light stability &lt; With the increase of the capacity of the recording medium, these problems become more important. In view of the above problems, review the functions that can give pore formation promotion, pore brake, and light safety. The use of various additives.
