Abstract

PURPOSE: To improve an error detection probability at a reproducing time by form recording word data easily by adding a prescribed error detection word to word data formed by plural words which are arranged in series in the order of sampling.
CONSTITUTION: Analogue signals of left and right channels, etc., are converted to PCM signals by sampling and are arranged in series at every fixed period such as a horizontal synchronous period together with word L1, which is formed by PCM signals in the order of sampling, word R2 of right PCM signals, parity word P1, etc., thereby forming word lines l1,.... When a check word such as a CRC based on expression I is added to each of lines l1..., the generation probability of words which accord to the combination of lines l1... generating drop-out at a reproducing time and have uncorrectable error is lowered, so that the error detection probability can be improved, and word lines can be formed easily at a recording time due to words arranged in series. Otherwise, the similar result is obtained even if the word arrangement in each line is changed.
