Title: Optical information recording and erasing methods
Inventor: KOBAYASHI TADASHI
IPC: G11B7/24
Filed: 1991-02-07
Abstract: PURPOSE:To simultaneously conduct the erasing and recording of a signal by irradiating a disk whose optical density is increased with quencing and reduced with annealing by two kinds of light with different power levels. CONSTITUTION:The recording layer of a phase change type optical disk is constructed so that its reflectance can be changed with the increase of optical density by means of quenching or the reduction of optical density by means of annealing after the rise of temperature due to heating. By utilizing modulation light at two levels of a blackening signal recording power level P2 and a whitening signal erasing power level P1, the blackening part (a) and the whitening (b) of an existing signal recording track is irradiateMhe light beams, respectively. When the part (a) is irradiated with the beam at the level P1, the part is changed into the whitening part (c) to be erased while the part (b) is not changed by the irradiation. To the contrary, when the part (b) is irradiated with the beam at the power level P2, it is changed into the blackening part (d) to be erased and a new signal bit is formed.
