PURPOSE:To obtain a high-sensitivity, long-life optical recording body which uses a low-output semiconductor laser while preventing the deformation of a resin plate and the oxidation of a recording film, by providing thin recording films, each consisting essentially of Te and C, on both sides of the organic resin plate which has low thermal conductivity. CONSTITUTION:On both surfaces of an organic resin substrate 3 with low thermal conductivity such as an acrylic resin plate having <=1X10<-3>cal/sec thermal conductivity, optical recording films 4 which consist essentially of Te and C while containing H and O are formed by sputtering Te in gaseous CH4, etc., obtaining an optical recording disk. Because both the surfaces of the resin plate 3 are covered with the films 4, neither curvature nor strain due to humidity and temperature is caused. Further, the films 4 never become transparent owing to oxidation and a high-sensitivity, long-life recording medium for optical recording and reading which uses a low-output semiconductor laser is obtained. |
