ABSTRACT:
An optical recording medium having a track including plural pits formed based on first data and lands defined between neighboring pits, these pits are deformed as they are recorded based on second data. The first and second data are synthesized and reproduced to realize audio reproduction with a broad frequency range. The first data are adapted to be reproducible by a customary disc reproduction device. The reproduction of the first data is controlled by the second data to protect recorded data.
