Title: Initialization method of optical recording medium
Inventor: WATANABE OSAMU
IPC: G11B7/0055
Filed: 1990-03-27
Abstract: PURPOSE:To obtain good CN and erasing rate by irradiating a recording layer with a specified laser beam to change the recording layer from an amorphous state to a crystal state. CONSTITUTION:The optical recording medium is irradiated with the laser beam having 0.5<=p<=5.0 power density P (mW/mum<2>) and 1<=T<=100 irradiation time T (musec) to change the recording layer from the amorphous state to the crystal state. The crystallization of the recording layer is obtd. by heating the recording layer to the temp. region above the crystallization temp. and holding the recording layer for the time necessary for the crystallization or above. The prolonging of this irradiation time by increasing the diameter of the laser beam results in the delayed heat outflow of the recording layer by a vapor deposition effect. The time for holding the temp. above the crystallization is thereby made further longer than the actual irradiation time and, therefore, the good erasing rate is obtd. and the excellent stability is obtd.

For example, when the original is discriminated to be a color original, a logical 1 signal is outputted and when the original is discriminated to be a black/white original, a logical 0 signal is outputted. Then a discrimination signal is inputted to the color/black-white conversion section 205 via a discrimination signal line 233 and the color/black-white conversion section 205 applies conversion depending on the discrimination signal. When the original is discriminated to be a black-white original, the black/white conversion is implemented.
