Title: Crosstalk sensor for optical video disc player
Inventor: IKOMA JUNICHI
IPC: G11B7/005
Filed: 1985-06-05
Abstract: PURPOSE:To detect a crosstalk with an inexpensive constitution by providing a means detecting the sum of the output current of a photo diode group for detecting the laser beams to read the video information recorded in a disc, and detecting that the minimum value of the said sum is the point of least crosstalk. CONSTITUTION:One of the anode couple of a quarter diode 1 that transforms the reflecting light from the disc to an electric current, is connected with a resistor 7 and with the positive-phase input terminal of an operational amplifier 8. If the resistance values of the resistors 7 and 10 are selected so as to equalize, the voltage at the connection point between the resistor 10 and the other anode couple becomes of a value which is the product of the difference of the D.C. current of one diode couple and that of the other diode couple, and the resistance value of the resistor 7 or one 10. This voltage is inputted to an operational amplifier 12 of voltage-follow connection via a resistor 11A for preventing interference with an FM amplifier 4, and is lead to an output terminal 13. By using this crosstalk detecting signal from the terminal 13, the amount of crosstalk is controlled at minimum.
