Parametric Sweep Measurement Definitions
7. Measure the distance between the center of the track (i.e, at zero offset) and the center
of the write track width. And denote the measured distance as read/write offset (RW
offset).

Measurement of Read Write Offset
8. Plot the original track profile at ±(Squeeze position) as an imaginary track profile as
shown in Figure 5-47.
9. Calculate the distance between the two interpolation lines at 0% threshold. Squeezed
OTRC is calculated as one-half the difference between the right and left interpolation
lines at floor level.
