PURPOSE:To reduce the noise due to the clogging of a head or an error in the tape driving direction having a certain width in the tape width direction, by allocating data on even and odd sample groups of the same channel for each scan and also recording those data at position separate from each other to the scanning direction. CONSTITUTION:In a record system the samples WL0, WR0, WL1, WR1... which are supplies successively after A/D conversion are written in an array as shown in the diagram. In other words, those samples are written with the sample address set at 0 and frame addresses set at 0, 8, 12, 4.... Then the sample address is replaced once, and the writing is carried out again with control given to the frame address when the frame address is set at 7 and after the sample of WR7 is written. In such a way, the samples are distributed in a matrix of (4X16). In this case, the odd and even sample groups are separated from each other for each channel. |
