Apparatus and method for recording and reproducing digital signals on first and second areas of a storage medium

摘要

A digital signal is recorded along tracks on a recording medium. Each of the tracks has plural areas. A portion of the digital signal which is recorded on a first area out of the plural areas includes information for reproduction of the digital signal. The information is recorded also on at least one of second areas out of the plural areas. The second areas are greater in size than the first area. The information includes, for example, subcode header information.
