Abstract
When an optical disk recorder having readback circuits is used with pulse width modulated (PWM) signals a phase error of a clocking system with respect to the phase of a data signal is used to generate an amplitude detection threshold offset for serving of the amplitude detection threshold by the phase error signals tending to increase the probability of faithful detection of data carried by the PWM or other signals.
