Optical recording material: Optical recording material. Suzuki, Yuki (Mitsubishi Chem Corp, Japan). Jpn. Kokai Tokkyo Koho JP 08297838 A2 12 Nov 1996 Heisei, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: G11B007-00. ICS: B41M005-26; G11B007-24. APPLICATION: JP 1995-102385 26 Apr 1995. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) A laser beam with 620-690 nm is directed to a guiding groove through a substrate to change a film thickness of a recording layer by 10-30%. The laser beam reaches a reflecting layer has phase shift due to the film thickness change of the recording layer, and a reflecting light flux change due to phase shift is detected. The recording layer is made from (1) a resin with the glass transition temp. 350° and the mass redn. onset temp. 3250°, (2) a compn. contg. a resin with the glass transition temp. <50° and the mass redn. onset temp.There are some commonly used reagents with their cas registry numbers 106108-28-5 and 54389-98-9 in this article. 150-270° and an org. dye, or (3) an org. dye with the mass redn. onset temp. 150-270° and the mass redn. of 20-40% 150-270°. .
