LASER DISK Meaning and
Definition
-
A laser disk, also commonly known as a LaserDisc, is a type of optical videodisc storage medium that revolutionized home entertainment in the late 1970s and early 1980s. It is essentially a large format analog optical disc that used a laser beam to read and play video and audio content.
The laser disk consists of a 12-inch (30-centimeter) diameter polycarbonate disc that resembled a vinyl record. It is coated with a reflective layer and then protected by a transparent plastic cover. The video and audio data are stored as microscopic grooves on the disc's surface. To play a LaserDisc, a compatible player is required, equipped with a laser pickup that reads these grooves when the disc is spinning.
Compared to traditional VHS tapes and Betamax, the LaserDisc format offered superior audio and video quality. It provided a higher resolution and wider color range, making it a popular choice among videophiles and film enthusiasts. Laser disks were also known for their durability, as they did not deteriorate with repeated viewings like magnetic tapes did.
Laser disks were often used for movies, concerts, educational programs, and other forms of multimedia content. However, the format faced stiff competition from the emergence of VHS tapes and later DVDs, ultimately leading to its decline in popularity by the late 1990s. Despite its relatively short span of popularity, the LaserDisc format played a significant role in the development of home video technology.

Etymology of LASER DISK
The term "laser disk" has its roots in the technology it refers to. The word "laser" is an acronym for "Light Amplification by Stimulated Emission of Radiation". It was first coined in the early 1960s when the technology was developed.
The term "disk" refers to the physical format used by LaserDiscs. LaserDiscs, also known as LaserVision, were a home video format introduced in the late 1970s and early 1980s. LaserDiscs used a magneto-optical system, where video and audio information was stored as small pits on the surface of the disc. These pits would be read by a laser beam, hence the "laser" aspect, and translated into audio and video signals.
Overall, the term "laser disk" is a combination of the technology behind the laser beam used to read the disc and the disc format itself.
