Conventional C2 coding and interleaving for multi-track data tape in LTO-¾ do not support recording data onto a number of concurrent tracks which is not a power of two. Higher-rate longer C2 codes, which do not degrade error rate performance, are provided. An adjustable format and interleaving scheme accommodates future tape drives in which the number of concurrent tracks is not necessarily a power of two. A data set is segmented into a plurality of unencoded subdata sets and parity bytes are generated for each row and column. The parameters of the C2 code include N2 as the least common multiple of the number of possible tracks to which codeword objects are to be written. COs are formed from N2 C1 codewords, mapped onto a logical data track according to information within headers of the CO and modulation encoded into synchronized COs which are written to the tape.

Error correction coding is provided for codeword headers in a data tape format, such as a Linear Tape-Open, Generation 4 (LTO-4) data tape format. The data tape format defines a codeword quad as having first and second codeword headers interleaved with first and second codeword pairs, each codeword header comprising N bytes Ck=C0, C1, . . . , CN−2, CN−1 wherein K bytes C0-CK−1 of the first and second headers in a codeword quad differ such that if one is known the other can be inferred. Each header byte Ck of a codeword quad is redefined as comprising two interleaved (M / 2)-bit nibbles, ek, ok. For each header, nibbles ek-eN−1 and nibbles ok-oN−1 are generated as a function of nibbles, e0-EK−1 and o0-oK−1, respectively. A codeword is assembled with the redefined headers the codeword quad is then recorded onto a recording medium.
