Title: Phase transition type optical recording medium
Inventor: UENO OSAMU
IPC: G11B7/24073
Filed: 1991-10-18
Abstract: PURPOSE:To improve an erasing rate by forming flat parts parallel with the base of the medium and inclined slope parts stop a recording layer. CONSTITUTION:The erasing rate increases as the width size d1 of the flat parts 3 decreases gradually from about 1mum. CN ratio degrades slightly if the size d1 is narrowed but the CN ratio of >= 45dB is sufficient in either case. The efficiency of preventing the degradation in the reproduction rate is more exhibited as the erasing rate increases. The erasing rate is high when the imcompletely erased part around the recording region is on the verge of the slope part 4 when the size d1 is smaller than 1mum. The light reflected in the imcompletely erased part is prevented from intruding into the reproduced signal in such a manner, by which the erasing rate is improved and the errors of information are decreased at the time of recording and reproducing.
