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