Abstract
When a linking-point indicating signal, a defect detection signal, and a peak detection signal are obtained, a switch control section controls the on/off states of switches such that the time constant of a filter section becomes smaller or larger than the standard value during the specified period. With this control, in a linking section or a period in which a reproduced signal is missing, the threshold for asymmetry compensation traces a signal state at a higher speed, or the preceding threshold is maintained irrespective of the state of an input signal.
