Partial response signaling with maximum likelihood detection (PRML) systems using a rate 11/12 punctured convolution code (PCC) as a recording code in digital magnetic recording are proposed. The bit error rate (BER) performance for several PRML systems for the rate 11/12PCC is obtained by computer simulation and compared with that for the conventional rate 8/9 code. It is shown that among these PRML systems, E2PR4ML systems for the rate 11/12PCC outperform those for the rate 8/9 code and provide an SNR advantage of about 3.4 dB at a BER of 10–4 and a normalized linear density of 3. © 1999 Scripta Technica, Electron Comm Jpn Pt 2, 82(5): 54–62, 1999
