In CAV mode the "×" number denotes the transfer rate at the outer edge of the disc, where it is a maximum. 20× was thought to be the maximum speed due to mechanical constraints until Samsung Electronics introduced the SCR-3230, a 32× CD-ROM drive which uses a ball bearing system to balance the spinning disc in the drive to reduce vibration ...
The Compact Disc File System (CDFS) is a file system for read-only and write-once CD-ROMs developed by Simson Garfinkel and J. Spencer Love at the MIT Media Lab between 1985 and 1986. [1] The file system provided for the creation, modification, renaming and deletion of files and directories on a write-once media.
Notable software applications that can access or manipulate disk image files are as follows, comparing their disk image handling ... CD, DVD, ISO, BIN, MDF+MDS ...
A CD-RW compact disc (CD-RWs) can be written, read, erased, and re-written. CD-RWs, as opposed to CDs, require specialized readers that have sensitive laser optics. Consequently, CD-RWs cannot be read in many CD readers built prior to the introduction of CD-RW. CD-ROM drives with a "MultiRead" certification are compatible.
CD-R (Compact disc-recordable) is a digital optical disc storage format. A CD-R disc is a compact disc that can only be written once and read arbitrarily many times. CD-R discs (CD-Rs) are readable by most CD readers manufactured prior to the introduction of CD-R, unlike CD-RW discs.
CDemu is a free and open-source virtual drive software, designed to emulate an optical drive and optical disc (including CD-ROMs and DVD-ROMs) on the Linux operating system.. As of 30 June 2019, CDemu is not available in the official repositories of Debian, Ubuntu and Fedora Linux for any release, but it is available via official PPA for Ubuntu and COPR for Fedora Linux.
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 ...
Sometimes disc images are even used to emulate the presence of a CD-ROM or DVD drive with the data entirely resident on the hard disc. For the command-line tool cdrdao, a so-called TOC file that can be authored inside a text editor is used to specify the details of the desired disc record. [1]
