OPTICAL INFORMATION RECORDING METHOD, OPTICAL INFORMATION RECORDING DEVICE AND OPTICAL INFORMATION RECORDING MEDIUM |
摘要 |
An edge position correction circuit corrects the edge positions of a recording pulse according to multi-valued information that determines the width of a mark. This allows the mark edges to be formed at the precise positions. Therefore, even if the mark having any width is recorded, multi-valued information can be recorded/reproduced accurately. <IMAGE> |
