RECORDABLE OPTICAL DISC, OPTICAL DISC RECORDING APPARATUS, OPTICAL DISC REPRODUCTION APPARATUS, AND METHOD FOR RECORDING DATA ONTO RECORDABLE OPTICAL DISC

摘要

An optical disk, which has a storage area is disclosed. Data is recorded and reproduced by emitting laser light into the storage area on the optical disk Power condition information and recording write strategy information which correspond to recording speed information for recording and reproducing data are recorded. The recording speed information is indicative of constant linear velocity and different linear velocity from the constant linear velocity.
