fs_offset
foffset
Thermal
Specifies the target lens position.
When fmode is set to 0,2,3,4 or 6 the autofocus servo uses the output signal
from the optical distance sensor to generate the necessary feedback for the
lens positioning control loop. The value of foffset is subtracted from the
output of the optical distance sensor to generate the focus error signal.
This parameter has no effect when fmode is set to 1.
Added to the foffset to form the total foffset is three times the "media sd"
value.
This value is used to adjust for the head dependent difference between write
laser focus and autofocus distance sensor zero point. The head dependent part
belongs in foffset but media dependent part should go into the "media sd"
setting.
