ABSTRACT:
A recording and reproducing timing generating apparatus records a preamble signal constructed by a predetermined bit pattern in which there is no recording pit before and after at least one clock before recording data. The generating apparatus controls a delay time of a sampling clock signal based on differential data of reproducing data sampled at timings before and after the recording pit of the preamble signal. The generating apparatus also controls the delay time of the sampling clock signal based on differential data of the reproducing data sampled at timings before and after the clock mark.
