Filed: 2001-08-24
Abstract: PROBLEM TO BE SOLVED: To reduce the risk of oscillation caused by loop characteristics when correcting a steep DC deviation in the PID area of a DVD-RAM at high speed by eliminating a feedback circuit configuration in a conventional binarizing circuit. SOLUTION: In the binarized signal generating method for generating a binarized signal from an information signal read out of an information recording medium on the basis of a binarizing threshold, the binarizing threshold is corrected to reduce a phase difference between the signal binarized by the binarizing threshold and a clock generated from the information signal by adding a value almost proportional to the phase difference to the binarizing threshold, and the binarized signal is generated from the information signal on the basis of the corrected binarizing threshold. The value almost proportional to the phase difference is delayed just for time almost equal with time required for calculating this value, and added to the binarizing threshold.
