Track Profile Measurement for a Micro Track (Micro Track Profile)
Measuring the track profile relative to micro track will allow you to compute the read head
width, as shown in Figure 5-42. From the illustration above the half amplitude width of the
micro track becomes the width of the read head.

Micro Track Profile Measurement
Fast Micro Track Profile Measurement
The fast micro track profile measurement is another method to make a micro track profile
measurement. The measurement speed is faster than one described in previous section.
This method creates a micro track by erasing side(s) of track at the specified width. There
is no level monitoring during erase. This method includes a sequence to create micro track
and to measure the narrow band TAA track profile. That is why the measurement speed is
faster. Detailed measurement sequence is described in the programming manual. See the
“hpe5022_measureMicroTrackProfile” function.
