The present invention provides an information recording and reproducing method of an information recording medium and an apparatus corresponding thereto. The information recording medium of the present invention includes radially wobbling groove portions having at least one of a substantially spiral-like track and concentric-shaped track. The information recording and reproducing method of this invention comprises the steps of generating a signal corresponding to the wobbling groove portions, and performing at least recording and reproducing information with use of an integer multiple clock of a frequency of the signal. Similarly, the present invention provides an apparatus for an information recording medium having radially wobbling groove portions which are provided with at least one of a substantially spiral-like track and concentric-shaped track. The apparatus of the present invention includes a wobble detecting circuit for generating a signal corresponding to the wobbling groove portions, and a clock generating means for generating an integer multiple clock of a frequency of the signal, wherein at least one of a record and reproduction is performed by using the clock.

Méthode d'enregistrement et de reproduction d'information, support d'enregistrement d'information et dispositif associé. Le support d'enregistrement comprend des sillons à ondulation radiale présentant soit une piste essentiellement en spirale, soit une piste de forme concentrique, ou les deux. La méthode d'enregistrement et de reproduction comprend les étapes suivantes : générer un signal correspondant aux sillons et exécuter au moins l'enregistrement et la reproduction d'information à l'aide d'un signal d'horloge correspondant à un multiple entier de la fréquence d'ondulation. De même, l'invention présente un dispositif destiné à un support d'enregistrement d'information présentant des sillons à ondulation radiale ayant soit une piste essentiellement en spirale, soit une piste de forme concentrique, ou les deux. Le dispositif comprend un circuit de détection d'ondulation pour générer un signal correspondant aux sillons, et un moyen de production d'un signal d'horloge pour générer un signal d'horloge multiple entier de la fréquence du signal, l'enregistrement et (ou) la reproduction étant exécuté au moyen du signal d'horloge.
