IPC: G11B11/10
Filed: 1989-03-31
Abstract: PURPOSE:To improve the sensitivity of signal reading and to easily execute the binarizing processing of a signal by amplifying the output voltages of respective photodetecting elements with respectively different amplification factors and then finding out the differential output of both the amplified outputs to increase the effective signal component of light quantity. CONSTITUTION:Decomposing means 9, 10 decompose reflected light from a magneto-optical recording medium 8 in a direction allowing the generation of a difference between P and S components. Two photodetecting means A, B detects two light beams respectively decomposed by the means 9, 10. Amplifying means 12A, 12B amplify respective outputs from the two elements A, B so that the output having a larger value of (signal component)/(light quantity) is amplified with an amplification factor larger than that applied to the other output. Then, a differential means 13 obtains a differential signal from the outputs of the means 12A, 12B. Thereby, the signal component ratio of the reading outputs can be increased without reducing the light quantity. Consequently, the signal reading sensitivity can be improved and the binarizing processing of a signal can be easily executed.

Title: Detecting circuit for tracking error signal of optical disk player
Inventor: NODA TSUTOMU
IPC: G11B7/09
Filed: 1982-05-19
Abstract: PURPOSE:To obtain the titled circuit with high reliability at low cost, by making the feedback resistance which is connected from the output of an operational amplifier to the negative-phase input coincide with the resistance which is grounded from the positive-phase input then detecting the output of each photodetector of positive-phase and negative-phase inputs respectively. CONSTITUTION:The current of a photodetector 6 is obtained in the form of voltage at an output 18 by a resistance 20 and an operational amplifier 19. If the current of the detector 6 flows toward the resistance 20, the voltage of the output 18 is negative and the voltage value is equal to a product of the current value of the detector 6 and the resistance value of the resistance 20. While the current of a photodetector 7 is converted into voltage by a resistance 21 and obtained at the output 18 via the amplifier 19. If the current of the detector 17 flows toward the resistance 21, the voltage of the output 18 is positive and the voltage value is equal to a product of the current value of the detector 7 and the resistance value of the resistance 21. As a result, the voltage obtained by giving a current-voltage conversion and a subtraction between current outputs of detectors 6 and 7 is obtained at the output 18. Thus it is possible to obtain a detecting circuit with high reliability at low cost.
