Abstract:
1. A recording apparatus for packing digital data that is input as packets each of which has a variable length to a block having a unit length of an error correction encoding process and encoding the packed block with error correction code that is a product code, comprising: means for packing data packets each of which has a variable length to a plurality of first blocks from the beginning thereof and packing an overflow portion of a data packet that is larger than the unit length to a blank portion of the first blocks to which a data block that is smaller than the unit length has been packed; means for generating a second block that contains a data packet whose length is 0 and the overflow portion; record data forming means for encoding a data block composed of a plurality of first blocks and a plurality of second blocks with error correction code that is a product code, adding a synchronous pattern and an ID to each block having the unit length, and forming record data; and recording means for recording the record data formed by said record data forming means to a record medium; wherein the overflow portion exceeding the unit length is successively stored in an overflow area of a memory; whereby said overflow portion of said data packet is detected on the basis of length information associated with said data packet.
