OTRC (Unsqueezed OTRC) Evaluation
d. Calculate "Squeezed OTRC" value from "Squeezed SNR[ ]" profile (see Figure
5-51).

9. "WW," "RW," "RW Offset," and "Squash" Evaluation
a. For the "Normalized OTRC Signal," specify the interpolation range which includes
the threshold and window size settings. Refer to Figure 3-80, "Best Fit Window,"
on page 135 for details.
b. Calculate the distance between the interpolation lines at 50% threshold and denote
the measured distance as the "Write Track Width (WW)."
c. Calculate the distance between the interpolation lines at 0% threshold (i.e., floor
level). Subtract the write track width from this result and denote the new width as
the "Read Track Width (RW)."
