Information recording carrier
专利汇可以提供Information recording carrier专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a stable information recording carrier having an excellent SN ratio by forming a coating film of metal having a high melting point and corrosion resistance on the surface of a base material made of an organic macromolecule where grooves are made, and then by further forming a layer of metal having high reflectivity or a high dielectric constant or base metal. CONSTITUTION:In one surface of a discoidal or tapelike base material 1 using an organic macromolecule such as vinyl chloride, grooves or lines of pits 2 for recording information are formed. On this surface, the 1st layer 3 is formed by vapor-depositing metal having a high melting point and high corrosion resistance and on the 1st layer, metal or base metal differing from the material selected for the 1st layer is vapor-deposited to form the 2nd layer 4. For the 1st layer, Ni, Co, Mn, Co, Mn, Ti, V, Ta, Nb, Mo, W, Hf, Zr, Au, Ag, Pt, etc., are usable. For the 2nd layer, Al, Sn, Ge, Sb, In, Te, As, Se, etc., are usable.，下面是Information recording carrier专利的具体信息内容。
