RECORDING MEDIUM, RECORDING METHOD, RECORDING DEVICE, AND REPRODUCTION METHOD AND REPRODUCER

摘要

A recording medium comprising a first area in which data error-corrected and encoded by a first error correction code is recorded, and a second area in which data error-corrected and encoded by the first error correction code and data decodable by a second error correction code different from the first error correction code are mixedly recorded. In the second area is recorded data whose accumulation value of DC component per unit time becomes biased when the data in the second area is reproduced.
