Abstract
A method and apparatus encoding and decoding data for storage on a mass storage device is described. The code used is a 5/6 rate code in which a maximum transition run constraint is imposed. This code is designed for use with an EEPR4 read channel and provides a Euclidian squared free distance, d,free, of 10 when used with an EEPR4 partial response filter and a Viterbi decoder.
