<storage, standard> (UDF) A CD-ROM file system standard
that is required for DVD ROMs. UDF is the OSTA's
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.
