Abstract:
A recording and reproducing apparatus comprising:an interleaving device comprising a memory for storing data and a memory controller for controlling writing and reading from the memory according to an interleaving pattern;a converter of data for recording for converting interleaved data received from the interleaving device into a signal suitable for recording on a recording medium having a plurality of tracks each having a plurality of blocks, each block having a plurality of sync blocks, where the data is interleaved among the plurality of tracks and encoded according to a first error correction code having a corresponding predetermined value t and encoded according to a second error correction code; anda reproduction apparatus comprising:a first error correction code decoder for decoding the first error correction code, correcting errors in the data, and providing a number of errors corrected by the first error correction code corresponding to each sync block;a memory for de-interleaving the data;a second error correction code decoder for decoding the second error correction code and outputting a correction disable signal corresponding to a sync block of the data if the second error correction code decoder did not correct an error in the data in the sync block; anda memory controller for preventing the memory from outputting the sync block having a corresponding correction disable signal also has a corresponding number of errors corrected greater than the predetermined number t.
