Title: Optical recording medium having many recording layers and its production
Inventor: KYON CHAN PARK
IPC: G11B7/24
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To enhance the light efficiency and to improve the reliability of reproduction and recording capacity of information by laminating and joining substrates in which recording layers are formed by forming recording materials having nonlinear optical characteristics varying in transmittance and/or reflectivity by the intensity of light on >=1 substrates of the plural substrate. SOLUTION: The first recording layer 12 provided with guide vallyes 12A existing between first and second light transparent layers 10 and 14 and the second recording layer 16 on the surface of the opposite second recording layer 14 are formed. The first recording layer 12 is formed of nonlinear reflection materials, such as a-Si, InSb and ZnTe, having the reflectivity nonlinearly increasing in proportion to the intensity of the light. Consequently, the light spot to the second recording layer 16 for from the light source does not focus at the first recording layer 12 near the light source, where the intensity of the light is weak, the transmittance is high and the reflected light quantity at the recording surface increase. As a result, the exact access of the second recording layer 16 is made possible and a high light efficiency and large recording capacity can be obtd.

Title: Metallic thin film magnetic recording medium
Inventor: TAKAHASHI SEIICHIRO
IPC: G11B5/725
Filed: 1985-06-06
Abstract: PURPOSE:To raise the resistance to wear and corrosion and traveling property of the title medium by providing a protective film of a specified long-chain polymer on a ferromagnetic metallic thin film. CONSTITUTION:A protective film of a long-chain polymer shown by the formula (R is 16-24 C alkyl and (n) is 1-50) is furnished in <=500 Angstrom  thickness on a ferromagnetic metallic thin film formed on an insulating film base of PET, etc. Such a protective film is formed by dissolving the polymer in a solvent such as toluene and coating the soln. When such a film is coated, the wear resistance and traveling property of a recording medium are enhanced by the appropriate film thickness as a consequence of the optimum concn. of the coating soln., the excellent lubricating action due to the long-chaia alkyl group and the strong adsorptive action of the maleic anhydride group on the metallic substrate. At the same time, the contact angle of the magnetic layer with water is augmented by the hydrophobicity of the long-chain alkyl group. Consequently, the intrusion of water causing the development of rust is prevented and the corrosion resistance is also enhanced.
