Information recording method and information recording apparatus

Abstract

An optical disc drive produces read gate signals for controlling the address and data read timing, and write gate signals for controlling the timing of data writing. During the disc speed is stable, the read gate signals and write gate signals are formed using the clock signal generated by an internal oscillator. However, when the disc speed becomes unstable, the read gates and write gates are formed using the clock signal generated by the signal reproduced from the disc.
