Abstract:
A data recording and reproducing device comprising:data recording means which records data divided into a plurality of blocks on a recording medium such that there is a gap area before or after each of the blocks; data reproducing means which reproduces data from the recording medium with a reproducing head to obtain reproduced data; and decoding means which decodes the reproduced data to obtain decoded data and outputs the decoded data; wherein a time required for the reproducing head to pass the gap area is shorter than a time required for the decoding means to decode the reproduced data; wherein the data recording means records data in one block based on a write data sector signal corresponding to the block; wherein the data reproducing means reproduces data from one block based on a read data sector signal corresponding to the block; and wherein a timing of the read data sector signal relative to the block is different from a timing of the write data sector signal relative to the block.
