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.
