A high speed, large capacity optical disk for commercial applications is developed. This disk system adopts both the pit-edge recording method and the MCAV method. New techniques, which can use these methods together and are suitable for interchangeability, are developed: Independent detection of leading/trailing edge and data composition. Consequently, the most reliable file system to date has been achieved.
