摘要：
of EP0323227 An information recording-reproducing method comprises the step of imparting an error correction code of M bytes and N bytes in a vertical direction and a horizontal direction, respectively, to data of m x n bytes, and producing a signal of (m + M) x (n + N) bytes (m, n, M and N being 1 or greater integer), the step of writing into a recording medium the signal to which the error correction code has been imparted, the step of reading out the written-in signal from the recording medium, the step of effecting error correction on the read-out signal in only one of the vertical direction and the horizontal direction by the use of the error correction code included in the signal, the step of judging that there has been abnormality in the writing-in when all the errors in the signal could not be corrected by the error correction in the one direction, the step of re-reading out from the recording medium the signal for which it has not been judged that there has been abnormality in the writing-in, and the step of effecting error correction on the re-read-out signal in the vertical direction and the horizontal direction by the use of the error correction code included in the signal and reproducing the data.
