ABSTRACT:
The present invention involves a method to transmit data over a communication channel that can be modelled as one of the three following partial response channels: dicode channel, PR4 channel and EPR4 channel. The method includes choosing a code, based on its algebraic structure, to obtain a desired minimum distance for the coded channel. A data sequence to be written to the storage medium is received and encoded according to the chosen code, to obtain encoded data. The encoded data is written to the storage medium.
