MiniDVD or 8 cm DVD (also "3 inch DVD") is a DVD disc with a reduced diameter of 8 centimetres (3.15 in). It has been most commonly used in camcorders due to its compact size. [ 1 ] The most common MiniDVDs are single layered and hold 1.4 GB of data, but there are variants that can offer up to 5.2 GB of storage space, through a combination of ...
All constant linear velocity transfer rates (read and write) of 2.0× on DVD-R/RW have been replaced with 2.4× in the specification for DVD+R/RW. Thus, specification sheets of optical drives list "2.4× CLV" instead of "2× CLV" as the base transfer rate level for DVD+R/RW. Earlier optical drives also have a 1.0× transfer rate level for both ...
Nearly all DV camcorders and decks have IEEE 1394 (FireWire, i.LINK) ports for digital video transfer. This is usually a two-way port, so that DV video data can be output to a computer (DV-out), or input from either a computer or another camcorder (DV-in). The DV-in capability makes it possible to copy edited DV video from a computer back onto ...
Early units supported only DVD-RAM and DVD-R discs, but newer units can record to DVD-R, DVD-RW, DVD+R, DVD+RW, DVD-R DL and DVD+R DL. Certain models include mechanical hard disk drive-based digital video recorders (DVRs) to improve ease of use. Standalone DVD recorders generally have basic DVD authoring software built in.
DVD-RAM (DVD Random Access Memory) is a DVD-based disc specification presented in 1996 by the DVD Forum, which specifies rewritable DVD-RAM media and the appropriate DVD writers. DVD-RAM media have been used in computers as well as camcorders and personal video recorders since 1998.
The player was marketed as an MP3 device, and the user was encouraged to burn MP3 music files to a mini CD, and then play them in the player, which was noticeably smaller than a standard portable CD player. The player could also play Red Book audio content burned onto mini CDs. It can play both CD-R and CD-RW media, as well as pressed mini CDs.
DVD-R DL and DVD+R DL discs receive a dye layer after curing, but before metallization. CD-R, DVD-R, and DVD+R discs receive the dye layer after pressing but before metallization. CD-RW, DVD-RW and DVD+RW receive a metal alloy layer sandwiched between 2 dielectric layers. HD-DVD is made in the same way as DVD.
The DVD-VR standard defines a logical format for video recording on DVD-R, DVD-RW, and DVD-RAM style media, including the dual layer versions of these media. As opposed to media recorded with the DVD+VR recording standard, the resulting media are not DVD-Video compliant, and do not play back in some DVD-Video players.
