Abstract
An information storage medium having a plurality of information storage layers, each of which includes an optimal power control (OPC) area for obtaining an optimal recording condition, wherein OPC areas in odd-numbered and even-numbered information storage layers are disposed not to face each other and not to contact each other, or partially overlap each other and lock out use of the overlapped portion. Therefore, when an OPC area of one information storage layer performs OPC, this OPC does not affect another information storage layer.
Claims12
A method of recording and/or reproducing data with respect to an information storage medium, the information storage medium comprising a first information storage layer comprising a first optimal power control area, a first reserved area, and a first defect management area, and a second information storage layer comprising a second optimal power control area, a second reserved area, and a second defect management area, the first optimal power control area of the first information storage layer being aligned with the second reserved area of the second information storage layer, and the second optimal power control area of the second information storage layer being aligned with the first reserved area of the first information storage layer, the recording and/or reproducing method comprising:
- recording data on at least one of the first and second optimal power control areas;
- and
- determining an optimal recording/reproducing power using the data read from the one of first and second optimal power control areas.
A method of recording and/or reproducing data with respect an information storage medium, the information storage medium comprising a first information storage layer comprising a first optimal power control area, a first reserved area, and a first defect management area, and a second information storage layer comprising a second optimal power control area, a second reserved area, and a second defect management area, the first optimal power control area of the first information storage layer being aligned with the second reserved area of the second information storage layer, the second optimal power control area of the second information storage layer being aligned with the first reserved area of the first information storage layer, and the first defect management area of the first information storage layer being aligned with the second defect management area of the second information storage layer, the recording and/or reproducing method comprising:
- recording data on at least one of the first and second optimal power control areas;
- and
- determining an optimal recording/reproducing power using the data read from the one of the first and second optimal power control areas.
