Focus/Tracking channel
The focus and tracking channel is the voltage control drive using BTL .
The focus and tracking is the same composition.
The relationship between the differential voltage between FOIN and REF and the output voltage is shown in following
Figure.
The voltage gain [Gvo] is 12.0[V/V].
