An optical disc that stores ana-log data in FM format for playback of movies and interactive multimedia content. These discs range in size from 8 inches to 12 inches. Laserdiscs are still employed in video training applications and for high-quality movie viewing, although DVD-Video now offers superior video characteristics.
A 12-inch disk that's similar to an audio CD but holds visual images (such as high-quality movies) as well as music. Also called a videodisc.
The older, larger format of digital storage for video. Preferred by collectors because films are usually presented in original widescreen format and there are often "extras" (director's commentary, trailers, documentaries, etc.) included. Compare to DVD.
A format for storing analog video signals on a 12-inch double-sided disc.
is an analog video format based on a large disc. Later versions of LaserDiscs support audio encoded as Dolby Digital or DTS surround sound. The DVD format is superior to that of LaserDisc, due to its digital, higher resolution MPEG-2 video encoding and higher data capacity (meaning you can watch a movie all the way through without having to manually "flip" the LaserDisc as with some movies). The LaserDisc format has been phased out due to the popularity of the DVD format. A few DVD players offer LaserDisc compatibility.

A precursor to DVDs, this analog format has been embraced by film buffs for more than a decade. Laserdiscs are LP-sized discs that usually must be flipped, and in some cases changed, in order to see an entire movie.
A plastic disk or platter on which text, video and graphic images can be encoded by means of microscopic pits engraved into the surface; also known as videodiscs. Laserdiscs are read by special players that transmit a laser beam onto the disks.
12-inch analog optical disc format produced from approximately 1978 to 2000, a niche format which appealed to cinemaphiles due to its higher video and audio quality, and the fact that many of the releases were oriented towards collectors (with higher video quality, OAR formatting, and extra features).
Large, metallic-looking records about the size of 33 RPM albums (12 inches in diameter), sometimes called videodiscs. Laserdiscs can store a vast amount of information in text, sound, and images. To play a laserdisc, you need a laserdisc player and either a computer monitor or television set. Laserdiscs come in two formats. CLV (constant linear velocity) is accessed by time and CAV (constant angular velocity) is accessed by frame number.

A video disc that holds thousands of video images and hours of sound. A 12-inch plastic disc used to store video, audio, and other data for playback on a video disc player and video monitor.
An optical disc, 12 or 8 inches in diameter, that can store video in analog form along with analog and digital audio signals in stereo and multichannel formats. The analog signals are frequency modulated. See: FM, CAV, CLV
A record-like storage medium that uses analog and laser optical technology to store up to 54,000 full colour still pictures and 30-60 minutes of full motion video on a disc. LaserDisc players can be controlled by computer and can provide random access to any segment on the disc within 1-3 seconds.
Before DVD there was laserdic. This large (12") optical disc, is about the size of an LP record but it is optical instead. Each disc holds audio and visual information like DVD, but each side is limited to only 60 minutes thus forcing most movies to be spanned over two sides and often over another disc as well. This was a big drawback, requiring the viewer to interrupt their viewing 2-3 times per movie. LD has same similar features to DVD, but not in the same quantity or quality that DVD offers. LD was the standard among movie afficionados looking for the best picture/audio available. Ever since DVD arrived though, LD has started to die and many collector's no longer add to their laserdisc libraries (A LD is considerably more expensive than an equivalent DVD).
12" consumer optical disc format used for the storage of audio and video signals. The laserdisc utilizes a high quality analog video signal capable of 400 lines of horizontal resolution as well as analog and/or digital audio tracks. Both CAV and CLV recording methods have been employed in the making of these discs over the years. The laserdisc has all but been replaced by the all digital DVD format.
Large 12-inch diameter optical digital format used for playing back images and sound.
A disc on which sound and visual images are recorded.
A video format which uses very large (12-inch) discs. The quality of the picture is better than VHS, but not as good as DVD.
The laserdisc (LD) was the first commercial optical disc storage medium, and was used primarily for the presentation of movies.
