The present invention provides remarkably improved availability in a data recording method and apparatus, a data recording medium, and a data reproducing method and apparatus. By recording additional information for data reproduction in each sector on a data reproducing medium as a subcode separately from data when the data is recorded in the unit of sector, reproduction of data can be controlled using the subcode, thus making it possible to remarkably improve the availability of the data recording medium.
