Optical disk, optical reproduction device, and optical recording device |
摘要 |
An optical disk has a recording track constituted by sectors arranged in a concentric or spiral form. Each sector is divided into segments, and each segment includes a data field where data is recorded and a clock mark field having a different light reflectance from that of the data field. The data field in the sector has synchronization patterns S. Hence, a highly reliable optical disk, optical reproduction device, and optical recording device can be offered that are capable of performing recording and reproduction even if a clock mark is defective due to a flaw.
