    • An optical recording/reproducing method and an optical recording medium capable of performing excellent optical recording with a simple structure in a recording layer made of environmentally friendly materials. The optical recording medium has a recording layer (18) formed on a substrate (12) and made of a mixture of a recording assist material and a dielectric material. A laser beam of which intensity is modulated in accordance with information to be recorded is irradiated onto this recording layer to cause a state change in the recording assist material and/or the dielectric material. The information can be recorded by changing optical characteristics thereof such as reflectivity. The recording assist material includes an element selected from Sn, Ti, Si, Bi, Ge, and C as a principle component, while the dielectric material as a base material for the dielectric layers is at least one of ZnS, SiO 2 , AlN, and Ta 2 O 5 .

    • An optical recording medium of phase change type, and in particular, a dual side medium prepared by adhering two single side media is provided. In this medium, deformation of record marks generated in the overwriting due to difference in light absorption between the record marks and the region other than the record marks is prevented by providing a reflective layer (5) of high light transmission, and increase in jitter and failure of track servo and focus servo caused by uneven coating of the adhesive layer (7) and the resin protective layer (8) are prevented. The optical recording medium comprises a substrate (2), a recording layer (4) of phase change type on the surface side of the substrate, and a reflective layer (5) and a light absorption layer (6) disposed in this order on the surface side of the recording layer. The light absorption layer has a light transmission of 85% or higher in wavelength range S (wavelength in the range of 400 to 450 nm), up to 55% at the recording/reproducing wavelength, and 80% or higher in wavelength range L (wavelength in the range of 800 to 830 nm).
    • 提供了一种相变型光学记录介质,特别是通过粘合两个单面介质而制备的双面介质。 在该介质中,通过设置高透光率的反射层(5),防止由于记录标记与除记录标记以外的区域之间的光吸收差异而在重写中产生的记录标记的变形, 防止了由粘合剂层(7)和树脂保护层(8)的不均匀涂覆引起的轨道伺服和聚焦伺服失败。 该光记录介质包括基板(2),基板表面侧的相变型记录层(4),以及在基板表面侧依次设置的反射层(5)和光吸收层(6) 记录层的表面侧。 光吸收层的波长范围S(波长400〜450nm)为85%以上,记录再现波长为55%,波长范围L(透过率)为80%以上 波长在800至830nm的范围内)。
