IPC: G11B7/28
Filed: 1998-12-09
Abstract: PURPOSE: An optical recording medium and a method for recording/playing back thereof are provided to have simple structure and to record by using low laser power. CONSTITUTION: A recording layer(2) is formed by coating liquid polymer for a thickness of 1000-3000 angstroms on a transparent plastic substrate(1) in a spin coating method for having a large absorbing rate in a blue band. A reflecting layer(3) is formed on the recording layer for the thickness of under 1000 angstroms in a sputtering method. A protecting film(4) is formed on the reflecting layer for producing an optical disk. To record, a laser beam of a blue wavelength band is irradiated to the recording layer, the liquid polymer molecules form an unevenness on the surface of the recording layer due to the change in volume. Then, zero and one are recorded by using the difference in reflecting rate due to the unevenness. To play back the recorded bits, the laser beam to play back is irradiated to the recording layer. When the laser beam passes the changed unit by recording the bit and the unchanged unit by not recording the bit, the difference in the reflecting rate is realized for playing back zero or one.
