Ratio
Specifies the ratio for micro track profile
measurement. When this ratio is reached the
erase offset will stop.Compares the TAA level
of micro track from the original track. This
ratio is defined as (TAA of Narrow Band
Micro Track Profile) / (TAA of Narrow Band
Track Profile). See “Micro Track Profile
Measurement” on page 286 for details.
3. Click the [Track Offset Compen Config.] button to open the Track Offset
Conpmenband window. This is the same as one in the track profile measurement.
4. Click on [Measure] button to start measurement.

Display
The Narrow Band Track Profile resulting from the original track and micro track are
both displayed on the window. The Write Track Width is computed from the results of
the Narrow Band Track whereas the Read Track Width is computed from the results of
the Micro Track.
NOTE
To observe the resulting waveform of the original track using the
“hpe5022_measureTrackProfile” function, set the sequence type as
“hpe5022_SEQ_ER_WR_M” and the measure function as “hpe5022_MEAS_NB_TAA”.
To create a micro track use the “hpe5022_createMicroTrack”function. To observe the
resulting waveform of the micro track using the “hpe5022_measureTrackProfile” function,
set the sequence type as “hpe5022_SEQ_M” so as not to erase the micro track.
5. Click the [Return] button to return to Measure menu.
