In the case of recording computer data, e.g., into clusters 16 to 27 of the data recording area, the range of clusters 16 to 27 is ensured as an available range in management table (parts table) of U-TOC. For example, onto parts table of No. 02h, such computer data is recorded as a segment in which cluster 16 is caused to be start address and cluster 27 is caused to be end address. For the purpose of carrying out management of recording state of computer data, FAT (File Allocation Table) is separately provided. At this table, management of recording states of clusters 16 to 27 is carried out. Thus, computer data can be recorded onto mini-disc for recording audio data.

Procédé de gestion d'un support d'enregistrement. Selon le procédé, les données numériques destinées au traitement informatique sont stockées sur un disque magnéto-optique habituellement utilisé pour l'enregistrement de données audio numériques condensées. Lorsqu'on enregistre des données informatiques dans les groupes (16-27) d'une zone d'enregistrement de données, l'étendue des groupes (16-27) est réservée à titre d'étendue disponible dans une table de gestion (table de pièces) d'U-TOC. Un segment est enregistré sur la table de pièces (02h) de sorte que le groupe (16) constitue l'adresse initiale et que le groupe (27) constitue l'adresse finale. Afin de permettre la gestion de l'état d'enregistrement des données informatiques, on prépare indépendamment une TAF (table d'affectation de fichiers) destinée à la gestion de l'état d'enregistrement des groupes (16-27).
