Power supply input for playback
and recording amplifiers
Integration output of automatic
tracking interface peak detection
signal for the playback mode. An
external capacitor is connected to
this pin for integration function.
Recording AGC detection. Con-
nected to an external capacitor for
the recording mode
Head amplifier damping adjust-
ment. Connected to an external
resistor
Recording current output for the
recording mode. Pin4 (EPCOM) is
terminated in the SP mode, and
Pin11 (SPCOM) is terminated in
the EP mode.
