virtual tape systemA peripheral unit that combines a disk cache and tape library to improve performance and eliminate cartridge waste. Also called a "virtual tape server," data intended for tape are written to the disk cache and later written to tape in the background. If a tape is read frequently, a certain amount of its data is held in the cache, which greatly improves access times over the slow loading process of a robotic library.
Tape files, no matter how small, are typically stored on one cartridge. A virtual tape system (VTS) provides volume stacking, which stores multiple files on a single volume. The virtual tape system indexes the files and manages them, dramatically improving cartridge efficiency. See virtual tape library.
VOB(Video OBbjects) A DVD movie file that contains MPEG video and AC-3 or other audio data. Audio streams for multiple languages are multiplexed together. VOB files have specific file names that start with VTS (Video Title Set) and contain title and section; for example: VTS_01_2.VOB means Title 1, Section 2. VIDEO_TS.VOB is the start of the content and typically contains menus and trailers. The IFO files contain the content's attributes and options (aspect ratio, subtitles, languages, etc.), and BUP files are backup IFO files.
