Connected to the pick-up photodiode
Added with FIN1 to create RF signal, subtracted with FIN1 to create FE signal
Connected to the pick-up photodiode
Connected to the pick-up photodiode Subtracted with F to create TE signal
Connected to the pick-up photodiode
DC component of the TE signal is input
Connects the TE signal gain setting resistor between TE pins
TE signal output
TES (Track Error Sense) comparator input. The TE signal is band-passed and input
Shock detection input
Tracking gain time constant setting
TA amplifier output
Creates a tracking phase compensation constant between TD and VR pins
Tracking phase compensation setting
Tracking jump signal (kick pulse) amplitude setting
Tracking control signal output
Focusing control signal output
Creates a focusing phase compensation constant between FD and FA pins
Creates a focusing phase compensation constant between FD- and FA- pins
Creates a focusing phase compensation constant between FA and FE pins
FE signal output
Connects the FE signal gain setting resistor between TE pins
Analog signal Ground
Single end output of CV+ and CV- pin signal
Spindle amplifier input
Gain setting resistor is connected when the spindle 12cm mode
Works together with the SPD pin to connect to the spindle phase compensation constant
Spindle control signal output
Sled phase compensation constant is connected
Sled control signal output
Sled feeding signal is input from the microprocessor
Sled feeding signal is input from the microprocessor
Tracking jump signal is input from the DSP
Tracking jump signal is input from the DSP
Tracking gain control signal is input from the DSP Gain becomes low when TGL is “H”
Tracking off control signal is input from the DSP
Tracking becomes off when TOFF is “H”
Outputs TES signal to the DSP
HFL (High Frequency Level) is used to determine whether the main beam is
positioned on a pit or a mirror
