Focus Servo
If the focus servo loop phase has been compensated, the focus servo loop mutts if the defect is. The focus error
signal at this time is differentiated by the 0.1uF capacitor to be connected to the terminal and the 470kohms
resistance and is output es through the servo loop. Therefore, the focus output is held to value before the defect
error during defect. The FSET terminal changes the at which the focus loop compensation is at its maximum.
If the resistance to VDDA connected to the terminal, the phase compensation frequency is changed 1.2kHz
below, and GND connected to the terminal, the frequency is changed 1.2kHz above.
During focus search, Fs4 turns on to cutoff the error signal and to output the focus search signal through the
FEO. When the focus is on, FS2 turns on, and the focus error signal input through the FSI is output through the
loop to the output pin.
