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.
Claims15
A recording and/or reproducing apparatus to record and/or read 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 disposed such that the first optimal power control area of the first information storage layer is 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 is aligned with the first reserved area of the first information storage layer, the recording and/or reproducing apparatus comprising:
- an optical pickup which records data on and/or reads the data from the information storage medium at an optical power;
- and
- a controller which controls the optical pickup to record and/or read the data with respect to the information storage medium, to record defect-related information in the first and/or second defect management areas, and to determine an optimum recording power at which to set the optical power during recording using the first and/or second optimal power control areas.
A recording and/or reproducing apparatus to record and/or read data with respect to an information recording 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 disposed such that the first optimal power control area of the first information storage layer is aligned with the second reserved area of the second information storage layer, the second optimal power control area of the second information storage layer is aligned with the first reserved area of the first information storage layer, and the first defect management area of the first information storage medium is aligned with the second defect management area of the second information storage medium, comprising:
- an optical pickup which records data on and/or reads the data from the information storage medium at an optical power;
- and
- a controller which controls the optical pickup to record and/or read the data with respect to the information storage medium, to record defect-related information in the first and/or second defect management areas, and to determine an optimum recording power at which to set the optical power during recording using the first and/or second optimal power control areas.
A multilayer 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,
- wherein:
- the first optimal power control area of the first information storage layer is 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 is aligned with the first reserved area of the first information storage layer.
A multilayer 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,
- wherein:
- the first optimal power control area of the first information storage layer is aligned with the second reserved area of the second information storage layer,
- the second optimal power control area of the second information storage layer is aligned with the first reserved area of the first information storage layer, and
- the first defect management area of the first information storage layer is aligned with the second defect management area of the second information storage layer.
