ABSTRACT:
A servo error signal generation circuit comprises a first sampling unit for sampling first detection signals at first sampling timings, a second sampling unit for sampling second detection signals at second sampling timings which are obtained by periodically thinning out the first sampling timings, an AD converter for analog-to-digital converting the data sampled by the first and second sampling units, and a completion unit for completing the sampling date of the timings which have been thinned out by the sub sampling timing generator, for the data which have been sampled by the second sampling unit and outputted from the AD converter.
