Abstract: PROBLEM TO BE SOLVED: To provide an enhanced technology to encode data stored on a magnetic medium such as a computer disk. SOLUTION: A code word of this invention has data bits of a 1st group and code bits denoting data bits of a 2nd group. The codes of this invention having the code word bike this can be processed at a high efficiency and causes less error propagation, being different from conventional codes.

Abstract: PROBLEM TO BE SOLVED: To provide an enhanced technology to recover information from a read signal. SOLUTION: The Viterbi detector of this invention receives a signal representing a sequence consisting of a plurality of values. The detector identifies a survivor path from a possible sequence value and periodically eliminates the identified survivor path with a prescribed parity to recover the sequence from the signal. The Viterbi detector as above can accurately recover data from a read signal with a deteriorated SNR by recognizing the parity being part of a data sequence and can increase a storage density of a storage disk of a disk drive.
