to
perform
this
adjustment
exactly,
However,
this

has
a
margin,
so
even
if
it
is
slightly
off,
there
is
no
problem.
Therefore,

perfrom
this
adjustment,
Focus/
tracking
gain
determines
the
pick-up
followup
(vertical
and
horizontal)
relative
to
mechanical
noise
and
mechanical
shock
when
the
2-axis
device
operate,
*
When
gain
is
high,
the
noise
when
the
2-axis
device
operates
increases,
*
When
gain
is
low,
it
is
more
susceptible
to
mechanical
shock
and
skipping
occurs
more
easily,
,
However,
as
these
reciprocate,
the
adjustment
is
at
the
point
where both are satisfied,
