Track #
Specifies the track number to be tested.
Offset Start
Specifies the starting point of the head offset
in measuring the TAA track profile.
Offset Stop
Specifies the stopping point of the head offset
in measuring the TAA track profile.
Offset Step
Specifies the step by which the head is moved
in measuring the TAA track profile. When you
set this parameter with [Offset Start] and
[Offset Stop], [Offset NOP] will be computed
and updated automatically.
Offset NOP
Specifies the number of measurement points
to build the track profile. When you set this
parameter with [Offset Start] and [Offset
Stop], [Offset Step] will be computed and
updated automatically.
Meas. Type
Specifies the type of measurement sequence.
1)[Erase Write Meas.] means to perform a DC
band erase, write data then measure. 2)[Write
Meas.] means to write data, then measure. 3)
[Meas.] means to measure only.
NOTE
When “hpe5022_SEQ_ER_WR_M” is selected in the “hpe5022_measureTrackProfile”
function, a DC erase is performed as erase sequence, however, when [Erase Write Meas.] is
selected, the band erase is performed in this VEE measurement program. In the VEE
measurement program perform, the “hpe5022_measureTrackProfile” function is done in
the mode of “hpe5022_SEQ_WR_M” after band erase.
4. Click the [Band Erase] button to open the band erase window. Band erase is executed
only when the selected measurement sequence in [Meas. Type] parameter is “Erase
Write Meas”.
