Abstract

L’invention concerne un dispositif de reproduction d’informations pouvant créer rapidement les informations de TOC (table of content, table des matières) utilisées ensuite pour effectuer des recherches tout en diminuant la durée avant le début de la reproduction de la première information de composition musicale, même dans le cas d’un disque partiel ne disposant pas d’informations TOC correspondant aux informations de composition musicale enregistrées. Le dispositif de reproduction d’informations détecte successivement des informations de composition musicale enregistrées sur le disque partiel (DK) dans l’ordre d’enregistrement des informations de composition musicale d’abord enregistrées, stocke temporairement les informations de composition musicale détectées dans une mémoire tampon (11A) dans l’ordre de détection et lit les informations de composition musicale stockées dans l’ordre de détection de façon à les reproduire. Pendant que s’exécute la lecture des informations de composition musicale dans la mémoire tampon (11A), des informations de composition musicale non détectées sont détectées dans le disque partiel (DK) et des informations de TOC générées en fonction du contenu de toutes les informations de composition musicale détectées et stockées sur le disque partiel (DK).
