The bit-error rate (BER) performance of 16/17(0,6/6) coded PRML systems for a single-layered perpendicular medium was studied by conducting read/write experiments using a spinstand system. The results show that the E3PR4ML system exhibits the best performance among the PRML systems evaluated in this paper, and achieves a BER of less than 10-6 at a high linear density such as 375 kbpi.
