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 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. 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. 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 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. The money so saved is spent on the addition of a protective layer necessary on blue ray DVDs and this causes the end price to be more or less same with the current price of a DVD.
