A processing of disc production is occurred disproportion because of modification of disc That is not reduced by only AC coupling The reference voltage of EFM comparator is controlled utilizing the fact that the generation probability 1 O is 50 duty in the binary EFM signal 8 APC AUTOMATIC POWER CONTROL CIRCUIT As the Laser diode has had large negative temperature characteristic when it does something for regularly supply current on laser diode Therefore the output on processing monitor photo diode must be controlled current for getting regularly output power 31 SERVO BLOCK 1 FOCUS SERVO PHASE COMPENSATION om 50 When the defect signal is detected the focus servo Loop is isolated this time the focus servo error output is outputted through low pass filter formed by connecting a capacitor 0 1uF between the built in 470KQ resistor and FDFCT Pin Pin58 Accordingly the focus error output is held as just before error value during the defect The peak frequency of the focus phase compensation is at about 1 2KHz when the resistor connected to PFSET Pin7 is 510KQ It is inversely proportional to the resistor connected to the Pin 7 32 While the focus search is operating the FS4 switch is and then focus error signal is isolated accordingly it is outputted by FSEO Pin Pin48 When the FS2 switch is ON the focus servo Loop is on and then focus error is outputted through the focus serv
