Abstract:
1. A system for integrating data and header protection in tape recording, the system comprising a processor and logic integrated with and/or executable by the processor, the logic being adapted to: provide a data array organized in rows and columns, each row of the data array comprising four interleaved C1 codewords (CWI-4); add a header to each row of the data array to form headerized rows, each header comprising a CWI-4 Designation (CWID) which indicates a location of the CWI-4 within the data array; calculate ECC parity for at least one C1 codeword in each of the headerized rows; and modify the headerized rows to include the ECC parity to form modified rows, wherein each modified row includes four interleaved codewords, at least one codeword being a C1′ codeword which includes ECC parity for a data portion of a C1 codeword and a portion of a header, and wherein none of the CWIDs are split across multiple C1′ codewords in a single modified row.
