The History Of DVA

History: Gauss E

DVA traces its beginnings to 1965 with the formation of Gauss Electrophysics, a company started by David Paul Gregg to pursue the storage of video information on optical disc media.  At the time, video information was stored on large reels of large-width magnetic tape.  Magnetic tape and the equipment used to read and record magnetic tape was expensive at that time, while VHS and Betamax tape systems were still years away from being created.

During the time that David Paul Gregg formed Gauss Electrophysics, MCA (the movie company) was interested in finding a suitable storage medium to mass market MCA's large movie library to consumers to allow people to watch MCA's movies in their homes.  MCA learned about the work being performed at Gauss Electrophysics and purchased the company in 1968.

History: DRAW

Two years later, in 1970, MCA built the first "direct read after write" (DRAW) optical disc recorder.  The MCA DRAW device was capable of reading information immediately after the information had been recorded to optical disc to confirm the quality of the recording.  Today, CD and DVD recorders  have become commonplace household items.  In 1970, however,  the MCA DRAW device was one of the few machines in the world capable of recording information to an optical disc.

In 1972 "MCA Discovision," as the company was then named, demonstrated the first replicated optical disc.  Until that time optical discs had primarily been used only in laboratory experiments.  The ability to replicate a disc proved that optical discs could become a viable commercial product.

History: Demo Picture 2 MCA Discovision also developed optical disc players during the same time that it had developed optical disc media.  In 1973, MCA Discovision demonstrated a "stop motion" feature, which allowed viewers to view a single frame of video information.  In 1974, MCA Discovision demonstrated the ability to access information randomly on an optical disc.  Both of those features proved that optical disc storage technology had capabilities that exceeded what could be done with magnetic tape.  Those features eventually helped make CD and DVD ROM storage devices become commercial products.

History: Universal Pioneer In 1976, MCA Discovision introduced the first Videodisc player to consumers. History: PR7820
History: Carson MCA developed the optical disc as a way to make its movie library available to consumers for viewing in their homes, prior to the proliferation of VHS systems.  MCA also pursued partner companies to help make optical disc players available for consumers to view MCA's movies.  In 1977, MCA partnered with Pioneer Electronics to create "Universal Pioneer", which introduced Universal Pioneer's first optical disc player in 1978.

MCA Discovision began the commercial production of optical discs at a new facility in Carson, California.

Recognizing that the optical disc technology had other uses in addition to allowing consumers to watch movies in their homes, MCA Discovision also pursued the use of optical disc in  the industrial sector, in education, and in the commercial sector as a mass storage data device.  General Motors used the optical disc system as an interactive sales tool that allowed car buyers to pick available car options to see what their car would look like with the selected options.

IBM became involved in MCA Discovision in 1979, recognizing the data storage potential of optical disc technology. The company changed its name to its current name, Discovision Associates or "DVA".

History: IBM DVA
History: Pioneer Carson

By the early 1980's, VHS and Betamax systems had become popular with consumers and the Carson plant was sold to Pioneer Electronics and Universal Pioneer.  While DVA had licensed its optical storage patents to various companies as early as the mid-1970's, DVA became largely a patent licensing company by the mid-1980's.

In 1989, Pioneer Electronics purchased the remaining interests of DVA, including DVA's patent portfolio.  Since that time, DVA has continued to operate as a separate patent licensing entity.

History: Gregg Patent

In 1998, the U.S. District Court for the District of Delaware ruled that industry standard CD discs infringed one of DVA's original patents on the Optical Disc.

Today, DVA continues to license its patent portfolio to both optical disc and optical disc player manufacturers.
