Abstract

PURPOSE:To improve the utility ratio of recording capacity by recording only marking data through a first recording medium into a second recording medium and removing signals in a prescribed period from the beginning of the reproduction signals of the second recording medium at the time of reproduction. CONSTITUTION:When second 256 data are accumulated, a buffer memory 5 writes precedent data while it sequentially reads addresses from an initial one, and transfers having read data to a data memory 7. Consequently, data D1 are stored in the data memory 7. At the time of reproduction, data D1 which have been read from the data memory 7 are cyclically written into the buffer memory 5. When first 256 data are accumulated in the buffer memory 5, it further writes precedent data, while it sequentially reads the addresses from the initial one, and supplies having read data to a decoder 8. Thus, the utility ratio of recording capacity can be improved.
