Abstract
A data reproduction device for reproducing a data recorded in a recording medium having a data area and an error correction area including only error correction code data. The areas are formed in the medium. The device comprises a memory device for memorizing the error correction code data of the error correction area and a control device for reading the data from the error correction area and memorizing the read data in the memory device prior to reproducing the data when the medium is installed in the reproducing device. When an error is included in a data reproduced from the data of the data area, the control device controls the reproducing device in such a way that an error correction code data corresponding to the data including the error is read from the memory device so as to correct the error of the data.
