Defect Circuit
After RFO signal inversion, bottom hold is carried out using only 2. Except, the bottom hold of holds the
coupling level just before the coupling. Differentiate this with the coupling, then level shift it. Compare the signals
to either direction to generate the defect detect signal.

APC Circuit
When the laser diode operates in electrostatic field, the laser output temperature highly negative so the monitor
photo diode controls the laser output at a fixed level. The laser control system is installed to absorb the deviation
of the disc reflection. System controls the laser power using the tracking summing signal of the side beam to a
fixed laser output.
