Abstract
An optical information reproduction apparatus has a section which scans with an optical beam an optical information recording medium in which information is recorded. The optical beam is modulated according to the information. From this modulated optical beam, the corresponding reproduction signal is generated, then binary-converted. A sampling clock synchronized with this binary-converted reproduction signal is generated. The binary-converted reproduction signal is sampled with the synchronized sampling clock to reproduce the information. The response of the sampling-clock generating section can be switched. This optical information reproduction apparatus enables reliable information reproduction.
