An optical recording medium (51) and an optical recording and reproduction device including the same, wherein the optical recording medium (51) comprises a substrate (61), a reflective layer (62) formed on the substrate (61), a recording layer (64) formed on the reflective layer (62), a first protective layer (65) formed on the recording layer (64) and a transparent heat radiating layer (66) formed on the first protective layer (65) for promoting dispersion of heat from the recording layer (64), and light is focused on the recording layer (64) from an optical system via a side at which the heat radiating layer (66) is formed to prevent heat buildup, erasure of recorded signals and damage to the optical recording medium. <IMAGE> |
