With the advent of the Compact Disc at the beginning of Nineteen Eighties, the world underwent a dramatic change. It provided great audio quality and the ability to hold six hundred and fifty megabytes of data as a giant step in data storing and retrieving. This was the first time people had access to pre-recorded, recordable and rewritable media at low costs. It allowed extensive copying and sharing out of audio.  However, in the 1990’s, the demand for higher storage capacities arose and led to the development of the DVD which was a 5 – 10 x increase in storage capacity.  Although it was a new technology, the new DVD format used the same form factor as the CD which facilitated the migration into the next generation format.  This added to the DVD’s success with consumers.

In the present day, blu ray discs have made still another upheaval.  This new optical disc format is a proud development of the Blu Ray Disc Association (BDA) that include HP, Dell, LG, Hitachi, Apple, Samsung, Panasonic, JVC, Sony, Mitsubishi, Philips, Pioneer, Sharp, Thomson, and TDK.   The BDA boasts 180 of the world’s leading consumer electronics, media and personal computer manufacturers.

Blu ray discs provide enhanced storing capabilities, i.e. twenty-five GB on single-layer and fifty GB on dual layer discs. It is the perfect definition of the ultimate user experience and allows the recording, rewriting, playback and distribution of high-definition videos.  The fact that the blu ray discs are based on the bare disc physical form factor renders it compatible with compact discs and DVDs.

Just as its name denotes, blu ray discs utilizes a blue-violet laser beam to read and write data instead of the red laser beam which is being used as per the available technology at present. A blue-violet laser (405nm) has a far shorter wavelength than a red laser (650nm) making it possible to focus the laser spot with superior precision.  The advantage of this is that, it permits data to be stored in less space since the data can be packed more tightly, which further, allows consumers to fit additional data on the disc even though it may be the same size as a CD or a DVD.

Several of the world’s prominent PC and video game makers, recording media and consumer electronics and music companies have taken up this technology today and Hollywood studios and various smaller studios have already taken interest in these latest blu ray discs with the results of some of them already announcing the release of their new flicks on blu ray discs.

In the past, High Definition DVDs and Blu Ray Discs were competing intensely about which would succeed the DVD.  With the results of blu ray discs being the winner, the attention has now been turned on the blu ray drives that will operate the blu ray discs.  As the name signifies, the blu ray technology makes use of blue-violet laser to access data whereas the available technology at present uses a red laser.  A blue-violet laser (405nm) which is very short in wavelength than a red laser(650nm)concentrates the laser spot with superb accuracy.  The plus point of this is that it allows data to be recorded in less space as the data can be stored compactly which gives the users to squeeze in more data on the disc though the size of the disc is akin to that of a CD/DVD. A single-layer HD-DVD disc only store 15 GB whereas single-layer blue ray DVDs can store 25 GB which is more than 2 hours of high-definition video and 13hours hours of standard video.A dual-layer HD-DVD can hold up to 30 GB whereas dual-layer blue ray DVDs can store 54 GB which is 4.5hours of high-definition video and more than 20hours of a standard video.

Blue ray discs are the perfect definition of the ultimate user experience.  It further allows the recording, rewriting, playback and distribution of high-definition videos. The blue ray discs have been founded on the bare disc physical form factor which makes it compatible with CDs and DVDs.

Blue ray discs are also light on the manufacturers since these are built by injection-molding process on a single 1.1-mm disc compared to the traditional which thereby reduces costs. The costs thus saved are spent on the addition of the shielding layer necessary on blue ray discs with the result that the end price being more or less the same as that of a DVD.  Blue ray discs also have a higher data transfer rate of 36Mbps than the DVD’s of today that transfer data at the speed of 10Mbps.  The meaning of this is that it takes just an hour and half to burn twenty-five GB of data onto a blue ray disc.

The conventional DVDs and CDs initially came into the market with merely read-only formats.  The blue ray discs however, plan to provide a wide range of formats that include BD-ROM (read only), BD-R (recordable) and BD-RE (rewritable).

This future optical disc format – BRD (Blue Ray DVDs is a remarkable invention of the BDA (Blu Ray Disc Association) that consists of TDK, Thomson, Sharp, Pioneer, Philips, Mitsubishi, Sony, JVC, Panasonic, Samsung, Apple, Hitachi, LG, Dell and HP.  The Blu Ray Disc Association has the globe’s most prominent manufacturers of PCs, consumer electronics and media.

The days of DVDs are numbered. With more and more people upgrading to HDTV to enjoy modern digital television, the need to store high-definition content is also on the rise.  But, DVDs support a resolution up to 720×480 pixels while high definition content resolutions are as high as 1920×1080 pixels. High definition video content also consumes a lot of hard drive space.  Two hours of HD content with data compression necessitates up to 22 GB of storage space while a DVD-18 disc (dual-sided dual-layer disc) has a storage capacity of only 17GB.

The answer to this issue has helped invent two brand-new technologies, namely High Definition DVD and Blue Ray DVDs, which are now locked in an intense battle to clinch market shares and become the successor to DVD.  Both these technologies are very similar in nature but the blue ray DVDs have an advantage since these boast a far higher storage capacity than the HD DVD. As the name denotes, the blue ray discs make use of a blue-violet laser to write and read data in contrast to the existing technology which makes use of red laser.  A blue-violet laser (405nm) has a far shorter wavelength than a red laser (650nm) making it feasible to focus the laser spot with superior precision.  The advantage of this is that, it permits data to be stored in less space since the data can be packed more tightly, which further, allows consumers to fit additional data on the disc even though it may be the same size as a CD or a DVD.
A single-layer HD-DVD disc only store 15 GB whereas single-layer blue ray DVDs can store 25 GB which is more than 2 hours of high-definition video and 13hours hours of standard video. A double-layer High Definition-DVD can store up to thirty GB whilst double-layer blue ray DVDs can hold fifty-four GB which is 4.5 hours of HD video and more than 20 hours of normal video.
