laserdisc

Laserdisc is a technology and the physical medium used in storing and providing programmed access to a large database of text, pictures, and other objects, including motion video and full multimedia presentations.

The laserdisc itself is 12 inches in diameter and holds much more information than a CD-ROM disk can currently hold. Laserdiscs require relatively expensive players and are more expensive to distribute than CD-ROM disks. However, for school and corporate education purposes and any presentation requiring a great deal of motion video and the ability to create scripted or programmed access to selected portions of the laserdisc, the technology can be useful.
