PURPOSE:To simplify the control for interleave processing in comparison with the interleave in the unit of byte by applying the arrangement processing such as interleaving where a burst error is scattered in the unit of word. CONSTITUTION:A reproduced digital data and a reproduced sub-coding signal are applied to a data converting circuit 19 from a buffer memory 13 and the reproduced data is converted into a serial signal form. The serial signal uses 32-bit as 1 word; first 4-bit is preamble, next 4-bit is an auxiliary bit to the data and the last 20-bit is the data. The word format is fed to an interface 20, where it is converted into a data format of the standard computer. Moreover, the data to a system controller 14 is supplied from a microcomputer system 21. An interpolation circuit 22 is connected to a demultiplexer 18 and corrects an error data not corrected for the error. |
