Optical recording technology was invented by David Paul Gregg and James Russell in and first patented in A consumer optical disc data format known as LaserDisc was developed in the United Statesand first came to market in Atlanta, Georgia in It used much larger discs than the later formats.

Due to the high cost of players and discs, consumer adoption of LaserDisc was very low in both North America and Europe, and was not widely used anywhere outside Japan and the more affluent areas of Southeast Asiasuch as Hong-KongSingaporeMalaysia and Taiwan.

DVD Versus VHS: The Surprising Truth

On August 14,an ad hoc group formed from five computer companies IBM, Apple, CompaqHewlett-Packardand Microsoft issued a press release stating that they would only accept a single format.

In one significant compromise, the MMCD and SD groups agreed to adopt proposal SD 9, which specified that both layers of the dual-layered disc be read from the same side—instead of proposal SD 10, which would have created a two-sided disc that users would have to turn over.

Philips and Sony decided that it was in their best interests to end the format war, and agreed to unify with companies backing the Super Density Disc to release a single format, with technologies from both. Adoption[ edit ] Movie and home entertainment distributors adopted the DVD format to replace the ubiquitous VHS tape as the primary consumer digital video distribution format.

Simultaneously, the movie studios decided to change their home entertainment release model from a rental model to a for purchase model,[ citation needed ] and large numbers of DVDs were sold.

At the same time, a demand for interactive design talent and services was created. Movies in the past had uniquely designed title sequences. DVD as a format had two qualities at the time that were not available in any other interactive medium: In addition, the medium itself was small enough and light enough to mail using general first class postage.

Almost overnight, this created a new business opportunity and model for business innovators to re-invent the home entertainment distribution model.

It also gave companies an inexpensive way to provide business and product information on full motion video through direct mail.

The MID contains data such as the manufacturer and model, byte capacity, allowed data rates also known as speedetc.

When played, a slight transition can sometimes be seen in the playback when the player changes layers. The drive with dual-layer capability accesses the second layer by shining the laser through the first semitransparent layer. In some DVD players, the layer change can exhibit a noticeable pause, up to several seconds.

The recording speeds reached by dual-layer media are still well below those of single-layer media. Track 1 then starts at the outside diameter. DVD video discs are mastered slightly differently. The video is divided between the layers such that layer 1 can be made to start at the same diameter that layer 0 finishes.

This speeds up the transition as the layer changes because although the laser does have to refocus on layer 1, it does not have to skip across the disc to find it.

In draft versions of the specification, DVD-5 indeed held five gigabytes, but some parameters were changed later on as explained above, so the capacity decreased.
