Home Theater Electronics - The Blu Ray Disc Formats

By Jim Howser


In 2006 the Blu Ray disc was shown to the world, and stands to be the next thing to replace the standard DVDs which are now in circulation.

Not that there is anything wrong with the DVD line of optical discs, Blu Ray discs just show to have more promise, as Blu Ray discs are capable of storing quite vast amounts of data figures, with its impressive storage capacity. This "extra space" is pretty much what made the DVD the best "replacement" against the CD in the first place, and stands to be the strong point for Blu Ray discs.

A single-layer DVD could store up to 4.7 gigabytes of data, while a dual-layer DVD could store up to 8.5 gigabytes of data. With Blu Ray formats, a single layer Blu Ray disc could store up to 25 gigabytes of data, while a dual-layer Blu Ray format disc could store up to 50 gigabytes of data.

As a medium for recording high definition movies, Blu Ray formats are simply amazing, and perfect for the job. Blu Ray formats are actually no different from the line of CD and DVD formats. There is the BD-ROM, the BD-R and the BD-RE. The BD-ROM of Blu Ray formats stands as the read only format of Blu Ray, ideal in the distribution of High Definition Movies, software for personal computers, as well as with games for personal computer systems and/or gaming consoles. The BD-R represents the recordable type of Blu Ray formats, perfect for recording High Definition movies, as well as large quantities of data. The BD-RE or Blu Ray formats is the rewritable type of Blu Ray Formats, capable of being erased and be used again.

The Blu Ray format is the result of the Blu-Ray Disc Association, which is basically composed of media manufacturers, computer makers and consumer electronics manufacturers from all over the world. The roster included in the Blu-Ray Disc Association includes giants like Sony, Pioneer, Samsung, Philips, LG, JVC, Hitachi, Thomson, Panasonic, Sharp, Apple, Hewlett Packard, Dell, and TDK.

With such consumer electronics giants backing up its fruition, it really isn't much of a wonder why Blu Ray and the different Blu Ray formats outperform DVDs, let alone the impressive storage capacities of Blu Ray optical disc formats.
