Universal Disk Format (UDF) 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.
Live File System lets users manage files on recordable and rewriteable optical discs inside the file manager with the familiar workflow known from mass storage media such as USB flash drives and external hard disk drives. Files can be added incrementally to the media, as well as modified, moved and deleted. [1] These discs use the UDF file ...
dvd+rw-tools (also known as growisofs, its main part) is a collection of open-source DVD and Blu-ray Disc tools for Linux, OpenBSD, NetBSD, FreeBSD, Solaris, HP-UX, IRIX, Windows and OS X. dvd+rw-tools does not operate on CD media. [1] The package itself requires another program which is used to create ISO 9660 images on the fly.
The DVD and Blu-ray discs hold a higher capacity of data, so reading or writing those discs in the same 74-minute time-frame requires a higher data transfer rate. Drive speed can be limited intentionally to reduce noise from the drive or slow down ripping , such as the firmware component Riplock .

Mac OS (8.6 or later) uses DVD-RAM directly. Windows XP uses DVD-RAM directly for FAT32-formatted discs only. Windows Vista is able to write directly to both FAT32- and UDF-formatted DVD-RAM discs from within Windows Explorer. Device drivers or other software are needed for earlier versions of Windows. Very fast access of small files on the disc.
Media Descriptor File (MDF) is a proprietary disc image file format developed for Alcohol 120%, an optical disc authoring program. Daemon Tools, CDemu, MagicISO, PowerDVD, and WinCDEmu can also read the MDF format. [1] [2] A disc image is a computer file replica of the computer files and file system of an optical disc.
It does not apply a file-based data recovery, as reading a defective medium at the file level means trying to read as much data as possible from each file. But a limitation of the file-based approach arises when data sectors are damaged which have book-keeping functions in the file system. The list of files on the medium may be truncated.
