Patent

CA 2407564

A method of recording address information by forming grooves wobbled with respect to an optical disk (5), comprising the step S1 of generating address information consisting of a synchronous signal, address data and address data error correction code, the step S2 of generating a phase modulation signal by multiplying a carrier signal by address information, and the step S3 of forming in the optical disk (5) grooves wobbled spirally and according to the phase modulation signal.

L'invention concerne un procédé pour enregistrer une information d'adresse par la réalisation de sillons formés par oscillation sur un disque optique (5). Ce procédé comprend les étapes suivantes : S1, générer une information d'adresse consistant en un signal synchronisé, une donnée d'adresse et un code de correction de donnée d'adresse ; S2, générer un signal de modulation de phase en multipliant un signal porteur par l'information d'adresse ; S3, façonner dans le disque optique (5) des sillons formés par oscillation en spirale, en fonction du signal de modulation de phase.
