FCircuit operation
(1)
Driver block
The input is the focus and tracking error signals from the
servo pre-amplifier and the control signals for the motor
system. The input signal is normally centered at 2.5V,
and at the pre-amplifier, it undergoes V / I conversion to
generate the current corresponding to the input voltage.
This is then passed through a resistor and sent to the in-
ternal reference voltage block.
This results in the output from the pre-amplifier being the
signal at the center of the internal reference voltage.
Furthermore, at the V / I conversion, forward and reverse
phases are generated and the BTL output is then gained
through the driver buffer.
(2)
Regulator block
The configuration is that of a normal series-type regulator
and the reference voltage is provided internally. A PNP
low-saturation transistor is connected externally.
