Specifies the speed at which data bits are
written on the media per second [bps].
Specifies the current applied to the write head.
Specifies the sense bias applied to the read
head.
Specifies the data pattern to the write head.
Specifies the track number to be tested.
Specifies the distance between the test track
and the adjacent track (i.e, squeezing track).
See measurement definitions on Chapter 4.
Specifies the distance where the write data
track is written. (not the same as squeezing
track). This distance is expressed as
percentage of the track pitch. See
measurement definitions on Chapter 4.
Specifies the type of measurement sequence.

band erase, write a specified data then
measure the parameter. 2)[Write Meas.] means
to write a data, then measure. 3) [Meas.]
means to measure only.
parameter. It is fixed to TAA in the SNA Triple Track
Specifies the use of best fit window. If
checked, the specified window size (%) will
be shifted between the high and low
thresholds in order to get the best correlation
to plot the interpolation lines. If unchecked,
the high and low threshold settings will be
used to plot the interpolation lines. Refer to
Figure 3-80 on page 135.
