Output terminal for focus error amplifier. Internally connected to window comparator
input for bias condition.
Input terminal for focus error.
Capacitor connection terminal for time constant used when there is defect.
This pin is connected to GND via capacitor when high frequency gain of the focus
servo is attenuated.
This is a pin where the time constant is externally connected to raise the low frequency
gain of the focus servo.
Focus drive output.
Focus amplifier inverted input pin.
This is a pin where the time constant is externally connected to generate the focus
search waveform.
This is a pin where the selection time constant is externally connected to set the
tracking servo the high frequency gain.
This is a pin where the selection time constant is externally connected to set the
tracking high frequency gain.
Pin for setting peak of the phase compensator of the focus tracking.
Tracking amplifier inverted input pin.
Tracking drive output.
Sled amplifier non-inverted input pin.
Sled amplifier inverted input pin.
Sled drive output.
The current which determines height of the focus search, track jump and sled kick is
input with external resistance connected.
Power supply.
“L” setting starts sled disorder-prevention circuit. (Not pull-up resistance)
