Mirror & Cpeak Mute (use only for tracking mute )
Used against ABEX-725A, this circuit processes the tracking mutting when mirror is detected.
(No recommend) the tracking mutting when EFM duty is above 22T after it is checked.
Mute does not operate in the following four cases.
Micom tracking gain up command transmission (TG1, TG2 = 1)
Anti-shock detection (ATSC)
Lock falls to L
Defect detection
TRCNT Output
TRCNT is output of mirror and TZC.
Mirror is the track movement detection output of the main beam; TZC is the track movement detection output of
the side beam. TRCNT receives these two inputs to determine whether the present pick-up is moving from the
inside to the outside or from the outside to the inside. It is used at $17 tracking brake operation.
