PURPOSE:To prevent the combustion gas of a recording film produced during recording onto an optical disk from attacking the recording film, and prevent the fragments of the recording film sticking to the recording film. CONSTITUTION:A space section 2 is filled with active carbon 7, and the combustion gas of a recording material 6, produced while data is recorded on to a recording film 4, is adsorbed by the active carbon 7, and the fragments of the recording material 6 also stick to the active carbon 7 without adhering to the opposite recording film 4. This allows the prevention of reading errors due to corrosion of the recording film 4 by the combustion gas and the sticking of fragments thereof to the recording film 4. |
