摘要：
In the phase change type optical recording medium of the present invention, loss of reliability by high-temperature storage is prevented, and self-erasure (a phenomenon of partial erasure of the record mark by heat diffusion in the lateral direction during the irradiation of the recording laser beam) is suppressed. There is thus provided an optical recording medium designed for use in a drive system wherein overwriting is conducted at a linear velocity V.sub.0 which satisfies the relation:0.6
