Blue Ray DVDs- Significant Invention of Blue Ray

Posted by on Wednesday, 23 December, 2009

This next generation optical disc format – Blue Ray DVDs – 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 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 BDA boasts 180 of the world’s leading consumer electronics, media and personal computer manufacturers.

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.  However, DVDs are known to support a resolution of 720 x 480 whereas HD content resolutions reach as higher as 1920 x 1080. HD video content uses up a considerable amount of hard drive space too.  High definition content with data compression of about 2 hours duration requires up to twenty-two GB of storage space whereas a DVD-18 disc (dual-sided double-layer) allows a storing capability of seventeen GB only.

The solution to this problem has let to the development of two technologies – HD DVD and Blue Ray DVDs – that are now in fierce competition with each to gain market share and become the successor of the DVD.  Though these two technologies are apparently similar to each other, the blue ray DVDs have a slight edge over the other as it boats of a greater amount of 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) carries a much lesser wavelength than a red laser.  The plus point in this is that as the data could be packed compactly it uses less space to store data and that fact lets users to add more data on the disc though the size of the disc is more or less the same as a CD/DVD.
A single-layer high definition DVD can hold only fifteen GB of data whilst single-layer blue ray DVDs can hold twenty-five GB which amounts to over two hours of HD video and thirteen hours of normal 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.

Blue ray DVDs 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 injection-molding process on a 0.6 mm (HD DVD follow the same method) which thereby reduces costs.  This savings balances out the expenses of adding the protective layer required on blue ray DVDs which means that the end price cannot be very different from the price of a regular DVD.

This future optical disc format – BRD (Blue Ray DVDs is a remarkable invention of the BDA (Blue 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.

DVDs, lets face it have its days counted. The necessity for storing HD content is increasing daily in the light of increasing number of people turning to HD television for their latest digital television fare. However, DVDs are known to support a resolution of 720 x 480 whereas HD content resolutions reach as higher as 1920 x 1080. HD video content uses up a considerable amount of hard drive space too. High definition content with data compression of about 2 hours duration requires up to twenty-two GB of storage space whereas a DVD-18 disc (dual-sided double-layer) allows a storing capability of seventeen GB only.

The blue ray discs, as the name suggests, uses a blue-violet laser to read and write data unlike the current technology which uses red laser. A blue-violet laser (405nm) carries a much lesser wavelength than a red laser. 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 high definition DVD can hold only fifteen GB of data whilst single-layer blue ray DVDs can hold twenty-five GB which amounts to over two hours of HD video and thirteen hours of normal video.

The days of DVDs are numbered.

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.
