Performance of TCPR in magnetic azimuth recording

The 8/10 DC-free code was developed into 8/10-PR1ML in azimuth recording. We previously discussed the performance of the 8/10 MSN code for Class 1 partial response (8/10 TCPR1) (1997). In this paper, TCPR1 and TCPR4 are applied to azimuth recording channels with cross-talk noise and white Gaussian noise. A simulated performance of several different user densities, azimuth angles and track pitches was carried out and the results presented. After determining suitable azimuth recording parameters for TCPR, we found a large off-track margin can be achieved on a removable medium such as magnetic tape.
