PERFORMANCE OF TCPR IN MAGNETIC AZIMUTH RECORDING

The 8/10 DC-free code was developed into 8/10-PR1ML in azimuth recordi ng.[1] We previously discussed the performance of the 8/10 MSN code fo r Class 1 partial response (8/10 TCPR1).[2][3] In this paper, TCPR1 an d TCPR4 are applied to azimuth recording channels with cross-talk nois e and white Gaussian noise. A simulated performance of several differe nt user densities, azimuth angles and track pitches was carried out an d 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.
