Evaluation of Write Track Width and Read Track Width
d. Calculate 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).”

Evaluation of Read Write Offset
e. Calculate “Squash” using the following equation:
Squash =
where,
TAAmax: “OTRC Signal[ ]” value at maximum TAA position
TAAsquash: “Squeezed Signal[ ]” value at “TAAmax” position
