In the second differential amplifier circuit 2, a resistance 12 is connected between the first differential amplifier circuit 1 and the negative input terminal, and a resistance 13 between the negative input terminal and an output terminal 11. The voltage gain of the voltage amplifier circuit is set by the voltage gain of the first differential amplifier circuit 1, which is decided by the resistant rate of the input resistance 4 and the negative feedback resistance 6, and the voltage gain of the second differential amplifier circuit 2, which is decided by the resistant rate of the input resistance 12 and the negative resistance 13. Thus, the voltage gain and the frequency characteristic can stably and optionally be set by the external terminals of the resistances and the capacitors.

Title: Optical information reproducing device
Inventor: SHIMAMOTO MASAMI
IPC: G11B7/09
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To improve the precision of detection of a tracking error by detecting the phase difference between two detection signals which change in phase relation according to the quantity of displacement of a light spot from the center of a track when one detection signal is state-inverted in the same direction within a prescribed time after the other detection signal is state-inverted. SOLUTION: An optical head 3 detects information recorded on an optical disk 1 and outputs detection signals (a) and (b). If the irradiation position of a light beam deviates from the information track center, the optical head 3 generates a phase difference between the two signals. Then 2nd waveform shaping means 41 and 42 remove low-frequency components from the detection signals (a) and (b), binarizes them, and outputs digital detection signals (c) and (d). A phase difference decision means 46 decides that both the signals are effective and outputs edge information when one of the two detection signals is state-inverted in the same direction within the prescribed time after the other detection signal is state-inverted. A tracking control means 5 cancels an error to make the light beam travel normally.
