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.
Selon le procédé, lors de l'enregistrement de données sur un support d'enregistrement dont l'unité d'enregistrement de données est le secteur, des informations supplémentaires concernant la reproduction des données sont enregistrées de façon distincte dans chaque secteur sous forme de sous-codes. Ces sous-codes permettent alors de gérer la reproduction des données. Cette technique accroît donc considérablement les possibilités d'utilisation du support d'enregistrement des données.
