Disk recording apparatus for controlling interruption of data and securing interleave length of first and last blocks of data after start and release of recording interruption

A disk recording system for recording data on a disk, comprising:

• a data processing circuit which receives data for each block and applies a predetermined process to the received data in units of a predetermined number of blocks to generate recording data to be recorded on the disk, said predetermined process including error correction;
• a recording controller for controlling interruption and release of interruption of data recording on the disk;
• and
• a data generator for generating predetermined specific data which is independent of the received data;
• wherein said data processing circuit secures the interleave length of the last block of the data received immediately before the interruption of recording by using the specific data generated by the data generator when applying said process to the last block, and secures the interleave length of the first block of the data received immediately after the release of recording interruption by using the specific data generated by the data generator when applying said process to the first block.
