OPTICAL RECORDING MEDIUM ON WHICH POWER INFORMATION OF ERASE PATTERN IS RECORDED |
摘要 |
An optical recording medium storing information about powers of an erase pulse is provided. The optical recording medium allows data to be recorded on, erased from, and reproduced from. In the optical recording medium, erase pattern information including information about power levels of start and last pulses of an erase pattern for erasing data is recorded. The start and last pulses of the erase pattern that can be differently set depending on kinds of recording layers of disks, kinds of disks, or each layer of a multi-layered recording layer are recorded in a reproducible only area of the optical recording medium. Thus, the time required for selecting an optimal erase power for the optical recording medium in which the recording apparatus is inserted can be considerably reduced.
