Abstract

PURPOSE:To enhance the correction capacity to a code error and to realize a low cost of a recorder, by alloting three tracks with every two channels and then carrying out a recording in a specified tape format. CONSTITUTION:The inspection word relating to the n-th word of each of the 1st and 2nd (such as L and R) channels which are recorded on the 1st and 2nd tracks respectively is turned into a vertical parity word Qnn to be used for the n-th word of the 3rd track. At the same time, the inspection words concerning each (2n-1)th word of the 1st-3rd tracks and the 2n-th word recorded at the place distant away from the (2n-1)th word by some plural words are used as the horizontal parity words to be recorded with an interleave at the place distance away from each 2n-th word of the 1st-3rd tracks. Then a code error detection/correction is carried out with every channel, and at the same time the double code error detecting function is provided for the parity relating to the 1st and 2nd channels.
