Abstract
An LDPC coding system includes a number of LDPC encoders and a number of LDPC decoders. The number of encoders/decoders is between one and one fewer than the total number of tracks on the high density tape are provided. The LDPC encoders are operable to break data from an incoming data sector into the data blocks to be written to the high density tape. The LDPC decoders are operable to assemble the data blocks into data sectors.
