Meaning of UNIVERSAL DISK FORMAT

 
Computing Dictionary
 
 Definition: 

(UDF) A cd-rom file system standard that is required for dvd roms. UDF is a replacement for the iso 9660 file system used on CD-ROMs, but will be mostly used on DVD. DVD multimedia disks use UDF to contain mpeg audio and video streams.

To read DVDs you need a DVD drive, the kernel driver for the drive, MPEG video support, and a UDF driver. DVDs containing both UDF filesystems and ISO 9660 filesystems can be read without UDF support.

UDF can also be used by cd-r and cd-rw recorders in packet writing mode.
