ABSTRACT:
The present invention relates to method and apparatus that records/reproduces data to/from an optical disk to rearrange user data such as video and/or audio data or to restore original data order by scanning each ECC block in a U-pattern. The present method arranges data in a data block in U-pattern scanning order on the block to randomize data sequence, and records the data block, of which data order has been randomized, sequentially along a track of a writable disk, whereby it is possible to recover individually a long burst error due to track-wise scratch, dust, fingerprint, or the like because an burst-error is scattered in a restored ECC block.
