Abstract
In one embodiment, a data storage system includes a write channel for writing data to a storage medium, the write channel configured to utilize a partial reverse concatenated modulation code. The write channel includes logic adapted for encoding data sets using a Cencoding scheme, logic adapted for adding a header to each subunit of the data sets, logic adapted for encoding the headers of the data sets with a first modulation encoding scheme, logic adapted for encoding data portions of the data sets with a second modulation encoding scheme, logic adapted for encoding portions of the one or more C-encoded data sets using a Cencoding scheme, logic adapted for combining the C-encoded portions with the modulation-encoded headers of the C-encoded data sets using a multiplexer, and logic adapted for writing the one or more combined C- and C-encoded data sets to data tracks.
