翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Universal Disk Format ： ウィキペディア英語版 Universal Disk Format Universal Disk Format (UDF) is a profile of the specification known as ISO/IEC 13346 and ECMA-167〔(ECMA-167 - Volume and File Structure for Write-Once and Rewritable Media using Non-Sequential Recording for Information Interchange )〕 and is an open vendor-neutral file system for computer data storage for a broad range of media. In practice, it has been most widely used for DVDs and newer optical disc formats, supplanting ISO 9660. Due to its design, it is very well suited for incremental updates on both recordable and (re)writable optical media. UDF is developed and maintained by the Optical Storage Technology Association (OSTA). Normally, authoring software will master a UDF file system in a batch process and write it to optical media in a single pass. But when packet writing to rewritable media, such as CD-RW, UDF allows files to be created, deleted and changed on-disc just as a general-purpose filesystem would on removable media like floppy disks and flash drives. This is also possible on write-once media, such as CD-R, but in that case the space occupied by the deleted files cannot be reclaimed (and instead becomes inaccessible). Multi-session mastering is also possible in UDF, though some implementations may be unable to read disks with multiple sessions.〔Multi-session mastering has always been part of the UDF specification. See (2.01/6.10.1 ), though earlier documents were not very clear that the anchor offsets are specified to be from the last session.〕 == History == The Optical Storage Technology Association standardized the UDF file system to form a common file system for all optical media: both for read-only media and for re-writable optical media. When first standardized, the UDF file system aimed to replace ISO 9660, allowing support for both read-only and writable media. After the release of the first version of UDF, the DVD Consortium adopted it as the official file system for DVD-Video and DVD-Audio.〔 (OSTA - UDF Specifications )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Universal Disk Format」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
