Abstract
A pattern discrimination method for error correction of 16/17 MTR code is d escribed for a high-density magnetic recording channel. It is based on the characteristics of bit-error patterns of the 16/17 MTR code, where frequent bit errors are restricted to several patterns. The difference between a pl ayback signal and an estimated signal is compared to the waveform patterns caused by the frequent error events. When the difference in the patterns is close to the error waveform, a corresponding decoding error is thought to have occurred and this error is corrected. Simulation results showed that t he use of this method improves performance by about 1.2 dB at a user record ing density (D-U) of 3.
