Tracking Error Amplifier

Each signal current from the photodiodes E and F is I-V converted and input to Pins 10 and 11 via an input

resistor which determines the gain. The signal is amplified by the gain amplifier, operated by the tracking error

amplifier and then the (F-E) signal is output to Pin 13.
