Abstract

PURPOSE: To obtain a high recording speed, a high erasing rate and C/N, the maintenance of stable operations in spite of repetition of many times of recording and erasing, excellent wet heat resistance and oxidation resistance, and a long life by forming reflection layers in two-layered constitution of different thermal conductivities.
CONSTITUTION: The reflection layers of the optical recording medium are constituted of two layers; the 1st reflection layer 5 and the 2nd reflection layer 6. The thermal conductivity of the 1st reflection layer 5 is set higher than the thermal conductivity of the 2nd reflection layer 6. The material of the 1st reflection layer 5 is formed by using metals, such as Al and Au, and the alloys essentially unsisting thereof, the Al added with Si, Mg, Cu, etc., or the Au added with Cr, Ag, Cu, etc., and the thickness thereof is specified to ≥10nm and ≤100nm. The material of the 2nd reflection layer 6 is formed by using metals, such as Ti, Zr, Hf, Cr, Mo, etc., and the thickness thereof is specified to ≥20nm and ≤200nm.
