The above figure shows a block diagram of the tracking and sled servo.
The capacitor connected between Pins 8 and 9 is a time constant to cut the high-frequency gain when TG2 is
OFF. The peak frequency of the tracking phase compensation is approximately 1.2kHz when a 510k
resistance connected to Pin 16.
To jump tracks in FWD and REV directions, turn TM3 or TM4 ON. During this time, the peak voltage applied to
the tracking coil is determined by the TM3 or TM4 current and the feedback resistance from Pin 12. To be
more specific,
Track jump peak voltage = TM3 (or TM4) current
×
feedback resistance
The FWD and REV sled kick is performed by turning TM5 or TM6 ON. During this time, the peak voltage
applied to the sled motor is determined by the TM5 or TM6 current and the feedback resistance from Pin 15;
Sled kick peak voltage = TM5 ( or TM6) current
×
feedback resistance
The values of the current for each switch are determined by the resistance connected between Pin 17 and
GND. When this resistance is 120k
:
TM3 ( or TM4) = ±11μA, and TM5 (or TM6) = ±22μA.
This current value is almost inversely proportional to the resistance and the variable range is approximately 5
to 40μA at TM3.
SSTOP is the ON/OFF detection signal for the limit SW of the linear motor's innermost track.
As is the case with the FE signal, the TE signal is switched to pass through a low-pass filter formed by the
internal resistance (470k
) and the capacitor connected to Pin 44.
TM-1 was ON at DFCT in the CXA1082 and CXA1182, but it does not operate in the CXA1372.
