Measurement of OTRC
14. Measure the distance between the two interpolations at the 0% threshold. And calculate
half the difference as OTRC (off-track read capability). As shown in Figure 5-49 the
the allowable OTRC is affected on how close the data tracks are written closer to the
adjacent track. It should also be noted that since the adjacent track is to overwrite the
previous written signal, it must be written at optimum write current. Otherwise, a poor
overwrite could result in residual signal that could affect or degrade the OTRC
performance of the head.
