The invention of DVD was all started in early of 1990s which two high-density optical storage standards were being technology advanced: the first one was the MultiMedia Compact Disc which was supported by Sony and Philips; and the second one was the Super Density disc which was approved and accepted by Time-Warner, Hitachi, Pioneer, JVC, Mitsubishi Electric, Toshiba, Thomson, and Matsushita Electric.
The IBM president named Lou Gertsner has exerted an effort to join and bring together the two companies to back up solitary standard, getting ahead a repeat of the expensive and inflated format war amongst Betamax and VHS in 1980s (Wikipedia, free encyclopedia. August 27, 2006). In 1994 of May, Philips and Sony promulgated that they would be willingly and jointly develop a newfangled high-density medium popularly known as Digital Video Disc or DVD.
This new technology was considered as the successor to compact discs or CD-ROM for computers and substitute laserdiscs and VHS tapes in the amusement industry. Just like a CD, DVD discs have similar diameter-about 120mm and thickness is about 1. 2 mm- just as Compact disc has but DVD is more advance and useful due to its capability to use both discs’ sides for data storage. The large video games which need and require a number of CDs would merely necessitate only one DVD disc.
Later on, newfangled technology’s development instantaneously induced dilemmas of a political nature. The Warner Home Entertainment and Toshiba declared their own project to work out the same but yet precisely distinct from DVD technology at the same time. Associations like the Hollywood Digital Video Disc Advisory Group had a sensible and rational interest in this technology’s development. Movie suppliers started to stir up disagreements and controversies which concern the essential of copy protections in the DVD requirement and description.
But then, Sony was the first to display its DVD technology. In 1995, John Eargle explained and illustrated the presentation which was conducted at the Winter Consumer Electronics Show. In his writings entitled “The Great DVD debate” stated that: “its color and sharpness was more than a match for the Laserdisc “. But Eargle’s attention was on the technological requirements which had been formally and legitimately promulgated in December of the same year.
The DVD’s intensification and enlargement data density was credited to a laser of a color advanced in the light spectrum and a technology that were being technologically advanced with 3M which permit the laser to be focus again to one second “layer” in the disc. It has a double-layer disc which amplifies the volume and dimensions to 7. 4 gigabytes. Throughout the spring of 1995, the disagreement of both developers had been stimulated through Toshiba’s personal growth and advancement of a two-layer disc named as SD or Super density (Chapin, R. “History of DVD”).
