Abstract:
1. A reproducing apparatus, comprising: an optical pickup which reads data from storage layers of a storage medium; and a controller which controls the optical pickup to read reproducing and/or recording speed information on the storage medium and to reproduce and/or record the data from the storage layers of the storage medium at a reproducing and/or recording speed, wherein each of the storage layers includes an optimal power control area for use in obtaining an optical recording condition, and one of a buffer area and a reserved area disposed at one side of the optimal power control area, and wherein the optimal power control areas in adjacent ones of the storage layers are disposed within different radii of the storage medium such that one of the buffer area and the reserved area disposed in one of the storage layers faces the optimal power control area disposed in an adjacent one of the storage layers.
