8.
TES and HFL (traverse signals)
When moving the pickup from the outer track to the inner track, the EF output from the pickup must be connected so that the
phase relationship of TES and HFL is as shown in the diagram below. For the TESI input, the TES comparator has negative
polarity and hysteresis of approximately ±100 mV. An external bandpass filter is needed in order to extract only the required
signal from the TE signal.
9.
DRF (luminous energy determination)
DRF goes high when the peak of the EFM signal (RFSM output) held by the PH1 (pin 60) capacitor exceeds approximately
2.1 V. The PH1 (pin 60) capacitor affects the DRF detection time constant and the RFAGC response bidirectional setting. The
DRF output is driven by a constant current (250 A).

10. Focus determination
Focus is assumed to be obtained when the focus error signal S curve reaching REF + 0.2 V is detected, and the S curve
subsequently returns to REF.
