RF AMP & SERVO SIGNAL PROCESSOR

MIRROR CIRCUIT
After amplifying the RFI signal, the mirror signal peak and bottom holds.
Peak hold can follow even at defect type
traverse and bottom hold counts the tracks by following RF envelop at a
jump. The mirror output is "L" on the disc track and "H" between tracks. Even if above 1.4 ms is detected, it
outputs "H".

EFM Comparator
The EFM Comparator makes the Rf signal into a secondary signal. The Asymmetry generated by a fault during
Disc production cannot be eliminated by only AC coupling, so control the standard voltage of the EFM
Comparator to eliminate it.
