Abstract: PURPOSE: A method for controlling a search of an optical recording medium is provided to decide only a signal over a reference level and over a reference pulse width as a TZC(Tracking Zero Crossing) signal. CONSTITUTION: A LPF(Low Pass Filter,301) makes a tracking error signal by low-pass filtering a read channel 2 signal from an RF(Radio Frequency) and servo error generating unit. A comparator(302) outputs the tracking error signal as a spherical wave by slicing with a predetermined slice level. A comparator(304) outputs the spherical wave as a TZC signal when a pulse width of the spherical wave is wider than a reference pulse width. Otherwise, the comparator(304) does not output the spherical wave. The spherical wave having a smaller pulse width is removed by filtering. Thereby, a number of TZC pulses conforming to a number of tracks are obtained.
