During the manufacture of an information storage medium, eccentricity may occur. For example, an information storage medium having a single information storage layer may have eccentricity of about 70-80 μm(p-p) (where p denotes a peak). To manufacture an information storage medium having first and second information storage layers L0 and L1, the first and second storage layers L0 and L1 are separately manufactured and then attached to each other. When eccentricity occurs during the manufacture of each of the first and second information storage layers L0 and L1, they may be attached to each other such that areas of the first information storage layer L0 are not aligned with those of the second information storage layer L1 as shown in FIG. 2B.
The first and second OPC areas 20_L0 and 20_L1 are disposed within different radii so that the first and second OPC areas 20_L0 and 20_L1 do not to face each other. In other words, the first OPC area 20_L0 faces a reserved area 30_L1, and the second OPC area 20_L1 faces a reserved area 30_L0.
The first buffer area 21_L0 is disposed on a side of the first OPC area 20_L0 that faces the outer boundary of the information storage medium, and the second buffer area 19_L1 is disposed on a side of the second OPC area 20_L1 that faces the inner boundary of the information storage medium. When the information storage medium has no eccentricity, the first and second buffer areas 21_L0 and 19_L1 face each other. The first and second buffer areas 21_L0 and 19_L1 have a length corresponding to at least the maximum eccentricity amount. The reserved areas 30_L0 and 30_L1 are disposed adjacent to the first and second buffer areas 21_L0 and 19_L1.
The first information storage layer L0 further includes a first protection area 51_L0 and a first OPC area 47_L0, between buffer areas 45_L0 and 48_L0. The second information storage layer L1 further includes buffer areas 45_L1 and 48_L1, a second protection area 51_L1, and a second reproduction-only area 50_L1. The buffer areas 45_L1 and 48_L1 are disposed at both sides of the second OPC area 47_L1.
FIG. 9 illustrates a variation of the dual-layered information storage medium of FIG. 8 in the dual-layered information storage medium of FIG. 9, a first information storage layer L0 includes the first reproduction-only area 50_L0 of FIG. 8, in which disk-related information for reproduction-only and disk control data for reproduction-only are recorded, and a first protection area 51_L0. A second information storage layer L1 includes an OPC area 47_L1 that faces the first reproduction-only area 50_L0. First and second buffer area 45_L1 and 49_L1 are disposed at both sides of the OPC area 47_L1. The information storage medium of FIG. 9 is different from that of FIG. 8 in that the second buffer area 49_L1 is sized to approximate the size of the second buffer 48_L1 of FIG. 8 and the second protection area 51_L1 of FIG. 8. As described above, the buffer area may have various sizes depending on its purpose, use, or the like.
an optical pickup which reproduces data from a storage medium including a plurality of storage layers; and
a controller which controls the optical pickup to read reproducing speed information from the storage medium and to reproduce the data from the different storage layers of the storage medium,
wherein each of the storage layers includes an optimal power control area used for obtaining an optimum recording condition, buffer areas and a reproduction-only area storing reproduction-only data, and
wherein the reproduction-only area of one of the storage layers is arranged to face the optical power control area and the buffer areas of an adjacent one of the storage layers.
2. The apparatus of claim 1, wherein the reproduction-only area of the one of the storage layers is larger than the optimal power control area of the adjacent one of the storage layers.
3. The apparatus of claim 1, wherein the buffer areas are disposed at both sides of each of the optimal power control areas.
a reader which reads data from a storage medium including a plurality of storage layers each having an optimal power control area, and at least one of a buffer area and a reserved area disposed at one side of the optimal power control area; and
a controller which controls the reader to read recording speed information from the storage medium and to record data from the storage layers of the storage medium at a recording speed,
wherein the optimal power control areas in adjacent ones of the storage layers are disposed at different radii of the storage medium such that one of the buffer area and the reserved area disposed in one of the storage layers is aligned with and faces the optimal power control area disposed in an adjacent one of the storage layers.
