CA 2485208

An optical disk and a method of recording data in the optical disk are provided. When data is overwritten on a recordable and/or reproducible optical disk, the method includes performing linking in front of a physical cluster from which overwriting starts. According to the method, when overwriting is performed on a portion of an optical disk in which data has been recorded, or when overwriting is performed on a portion including a defective area, linking is performed in front of the portion on which the overwriting is performed or behind the defective area, thereby realizing reliable data recording and reproducing.

L'invention concerne un disque optique et un procédé d'enregistrement de données sur un tel disque. Lorsque des données sont écrasées sur un disque optique enregistrable et/ou reproductible, le procédé consiste à effectuer des liaisons en face d'un groupe physique à partir duquel l'écrasement débute. Selon le procédé de l'invention, lorsque l'écrasement est réalisé sur une partie d'un disque optique dans lequel les données ont été enregistrées, ou lorsque l'écrasement est réalisé sur une partie comprenant des zones défectueuses, une liaison est effectuée en face de la partie sur laquelle l'écrasement est réalisé ou derrière la zone défectueuse, permettant ainsi un enregistrement et une reproduction fiables des données.
