Tracking Balance is carried out in the following manner. The GAIN of the F signaling AMP is adjusted by the
T_BAL (Tracking Balance) so that the AC level of the E, F signal input becomes the same.
After the BALANCE has been adjusted, the E,F signal is operated on in the 3-Beam Tracking Error Amp by TE =
k (E-F). Then the GAIN is compensated by Address 02H's GAIN_TE3 from 6dB - 20dB to compensate for the
difference in disc reflectivity according to disc type. The OFFSET is compensated by TE0FST, and the signal is
output as a TE3B signal.
The TE3B signal is output when the TE_SEL selects either the DPD TE or the 3B TE output.
The MUX TE output signal is output through the LPF (fc=20.4kHz) and the 10dB Amp.
The Servo Control voltage output is compatible with the 3.3V Supply.

The (A+C), (B+D) input signal is operated on in the FOCUS Error Amp by FE = -k((A+C)-(B+D)). The gain is
compensated by Address 03H's FE_GAIN from -2dB - +28dB to account for the difference in disc reflectivity
according to disc type. When the OFFSET is adjusted by FEOFST, the signal is output as an FE signal after
passing through the LPF (fc=34.7kHz) and the Inversion AMP.
The output is a Servo Control voltage and is compatible with the 3.3V Supply.
