I/O
For the connection of the pickup photodiode. Addition to the FIN1 pin creates an RF signal
O
and subtraction from it create an EF signal.
O
For the connection of the pickup photodiode.
O
For the connection of the pickup photodiode. Subtraction from the F pin creates a TE signal.
O
For the connection of the pickup photodiode.
I
Inputs the DC components in the TE signal.
For the connection of a resistor which sets the gain of the TE signal between this pin and the
O
TE pin.
O
TE signal output.
I
TES (track error sense) comparator input. The signal is passed through a BPF.
I
Shock detection input.
I
Sets the time constant for the tracking gain.
O
TA amp output.
I
Composes the tracking phase compensation constant between the TD and VR pins.
I
Sets the tracking phase compensation.
I
Sets the amplitude of the tracking jump signal (kick pulses).
O
Tracking control signal output.
O
Focusing control signal output.
I
Composes the focusing phase compensation constant between the FD and FA pins.
O
Composes the focusing phase compensation constant between the FD and FA pins.
I
Composes the focusing phase compensation constant between the FD and FA pins.
O
FE signal output.
For the connection of a resistor which sets the gain of the FE signal between this pin and the
I
TE pin.
O
Ground of analog signals.
-
Not connected.
O
Single-ended output of the signal input to the CV+ and CV- pins.
I
For the connection of a resistor which sets the gain in the spindle 12cm mode.
I
For the connection of the spindle phase compensation constant with the SPD pin.
O
Spindle control signal output.
I
For the connection of sled phase compensation constant.
O
Sled control signal output.
I
Sled feed signal input from the microprocessor .
I
Tracking signal input from the DSP.
I
Tracking gain control signal input from the DSP. Low gain when TGL is "H".
I
Tracking off control signal input from the DSP. Off when TOFF is "H".
O
Output the TES signal to the DSP.
