Abstract:
1. A data recording device that carries out encoding procedures including a bit order rearranging procedure for changing the bit order in data in a process of generating a data bit string to be written onto a recording medium from original data, said data recording device comprising: a data bit string combining unit that combines a data bit string obtained prior to a change to the bit order in the bit order rearranging procedure with a plurality of parity bit strings, one by one, by predetermined combining rules, so as to generate a plurality of composite data bit strings; and a data bit string selecting unit that selects one encoded data bit string, by predetermined criteria, from a plurality of encoded data bit strings generated by carrying out the encoding procedures including the bit order rearranging procedure for each of the plurality of composite data bit strings obtained from the data bit string combining unit, said data recording device performing a data write operation onto the recording medium in accordance with the one encoded data bit string selected by the data bit string selecting unit.
