PURPOSE:To confirm the normality of conversion data by providing a block detecting circuit for detecting the partition of a block of recording data and providing a RAM for storing the data of every one block on the outside of a microcomputer. CONSTITUTION:Data outputted from a recording data reproducing device 1 is received by a recording data converter 2. Byte data outputted from a reception control circuit 4 is stored in the part concerned of an address shown by an address counter in a RAM 12 or 13, and also, stored in a block detecting circuit, as well. When the partition of one block of the stored data is detected, a block detecting circuit 14 generates an interruption to a microcomputer 7. The computer 7 switches an address selecting circuit 10 or 11, and the RAM 12 or 13, and resets the counter 9. Subsequently, the contents which are read from the RAM 12 or 13 are outputted to a transmission control circuit 8, and also, the normality of the data is decided by reading a recording section number versus the number of bytes from a ROM 16. |
