ABSTRACT:
In an optical information accessing system for an optical disk including a plurality of sectors each having sector mark, a read operation is carried out by a sector mark detection signal when this signal is generated, and is carried out by a sector mark interpolation signal when the sector mark detection signal is not generated. When the sector mark detection signal is generated, the sector mark interpolation signal is masked, while, when the sector mark interpolation signal is not masked, the sector mark detection signal is invalidated.
