7-1 (4) Data setting for servos
[1] Data write (DTMS)
Various features can be achieved by writing various characteristics of the optical servo system from
an external microcomputer to this IC.
ɹ DTMS command is used to write the data such as servo parameters.
(Application)
(A) Setting of automatic adjustment value
(B) Setting of the optical servo loop characteristics including the characteristics for anti-vibration
(C) Setting of gain crossover for the optical servo loop
(D) Mode selection for anti-vibration
(E) Various system settings
(F) Various settings for optical servo system
(G) Access command setting
(MDATA format)

Note)
ɾUse the DTMS command in the STANDBY or PLAY mode.
ɾIf you write data successively, wait at least 25 µs before each data writing so that the microcomputer
finishes DSP processing and becomes ready for writing next data.
