Abstract

A recording medium and a method for recording and reproducing data on and from the recording medium are provided. Identification information, indicating which one of an in-groove recording method and an on-groove recording method has been or will be used to record data, is recorded in a specific area, such as a Burst Cutting Area (BCA) and a Permanent Information & Control data (PIC) area, of a recording medium such as a Blue-ray Disc (BD) on which a land and a groove are formed. The on-groove recording method or the in-groove recording method selected based on the identification information recorded in the specific area is used to record or reproduce data on or from the recording medium. This allows the in-groove recording method to be backward-compatibly applied to recording media.

Description

technical field [0001] The present invention relates to a recording medium such as a Blu-ray Disc (BD) on which lands and grooves are formed, and a method for recording and reproducing data on and from the recording medium. Background technique [0002] As the standardization of new high-density optical discs capable of storing ultra-long high-quality audio and video data, such as Blu-ray Disc Rewritable (BD-RE), progresses rapidly, a large number of related products are expected to be developed and commercialized in the near future. [0003] Such as figure 1 As shown in , BD-RE has a disc structure in which a clamp area, a transition area, a burst cut area (BCA) and a lead-in area are sequentially arranged inside the disc, a data area is arranged in the middle part of the disc, and a A lead-out area is arranged on the peripheral portion of the disc. [0004] The lead-in area is divided into a first guard (Guard 1) area, a permanent information & control data (PIC) area, a...
