IPC: G11B7/085
Filed: 1988-04-21
Abstract: PURPOSE:To always attain jump operation by inputting a tracking error signal to a phase advancing circuit, advancing a phase and comparing the phase with a reference potential. CONSTITUTION:The tracking error signal to be outputted from an amplifying circuit 15 obtains a maximum value or a minimum value in the edge of a track when a light flux crosses the track. When this signal is inputted to a phase advancing circuit 17, an output is advanced by 90 deg. to an input and goes to a signal, which crosses a GND level, in the edge of the track. In a timing detecting circuit 18, an input signal from the circuit 17 and the GND level, which is the reference potential, are compared by a comparator 18-1. Then, when the input signal crosses the GND level, the output of the output signal is inverted. This output is inputted to a jump pulse generating circuit 19 and in the circuit 19, the jump pulse signal of a pulse width by the input signal is generated. This signal is added to the output of a tracking servo circuit and the stable jump operation is executed.
