(Main)ID format for 50 mm magneto-optical disc system
ID format for 50 mm magneto-optical disc system
specifies the characteristics of 50 mm Optical Disc Cartridges (ODC) with a capacity of 730 Mbytes per Cartridge. This regulation covers the logical format of removable 50 mm magneto-optical discs used on digital still cameras, digital movie cameras, electronic albums and similar devices and combinations of these devices that record, play or process the digital data of still pictures, motion pictures and audio. This standard specifies the recording and reproducing format and processing method of files of still pictures, motion pictures and audio on 50 mm magneto-optical discs so that the users can use these discs on various compatible devices.

Format de l'Identifiant pour un système à disque magnéto-optique de 50 mm
La CEI 62345:2005 spécifie les caractéristiques des cartouches de disque optique (ODC) de 50 mm d'une capacité de 730 Mo par cartouche. Cette réglementation recouvre le format logique des disques magnéto-optiques amovibles de 50 mm utilisés sur des appareils photographiques numériques, des caméras vidéo numériques, des albums électroniques et des dispositifs similaires ainsi que des combinaisons de ces dispositifs qui enregistrent, lisent ou traitent les données numériques d'images fixes, d'images animées et d'audio. La présente norme spécifie le format d'enregistrement et de reproduction et la méthode de traitement de fichiers d'images fixes, d'images animées et d'audio sur des disques magnéto-optiques de 50 mm, de façon que les utilisateurs puissent utiliser ces disques sur divers dispositifs compatibles. La présente version bilingue (2012-11) correspond à la version anglaise monolingue publiée en 2005-09.
