SFID:
SLED servo filter input can be obtained not from SLD in Reg, but from M0D, which is the TRK
filter second-stage output.
When the low-frequency component of the tracking error signal obtained from the RF amplifier
is attenuated, the low frequency can be amplified and input to the SLD servo filter.
Only during TRK servo gain up2 operation, coefficient K30 is used instead of K00. Normally,
the DC gain between the TE input pin and M0D changes for TRK filter gain normal and gain
up2, creating a difference in the DC level at M0D. In this case, the DC level of the signal
transmitted to M00 can be kept uniform by adjusting the K30 value even during the above
switching.
TRK hold filter input can be obtained not from SLD in Reg, but from M0D, which is the TRK
filter second-stage output.
When signals other than the tracking error signal from the RF amplifier are input to the SE
input pin, the signal transmitted from the TE pin can be obtained as the TRK hold filter input.
Only during TRK servo gain up2 operation, coefficient K46 is used instead of K40. Normally,
the DC gain between the TE input pin and M0D changes for TRK filter gain normal and gain
up2, creating a difference in the DC level at M0D. In this case, the DC level of the signal
transmitted to M18 can be kept uniform by adjusting the K46 value even during the above
switching.

See "§ 5-20. Filter Composition" regarding the SFID, SFSK, THID and THSK commands.
TLD0 to 2:
These turn on and off SLD filter correction independently of the TRK filter.
See $38 (TLC0 to 2) and Fig. 5-3.
