Blu ray technology has been the answer for this problem.  This technology makes use of similar MPEG-2 compression standard as DTV making it greatly compatible with the international standard for digital broadcasting.  A dual-layer Blu-ray disk with 50GB can hold up to six hours of high definition content.  Though blu ray players are now available in the US and are more than capable of playing such high definition content, these lack the facility for recording high-definition content.

For this end, blu ray recorders have been created.  These recorders use a 36Mbps data transfer rate which is adequate to record and playback digital high-definition transmissions while still preserving the original picture quality. A blu ray disc recorder if fully utilized, can playback pre-recorded video on a disc and simultaneously record high-definition video broadcasted on TV.

Blu ray recorders are presently on sale only in Japan and began as a remarkable innovation in digital broadcasting.  Some of the many manufacturers of blu ray recorders include Amex, Hitachi, JVC, Mitsubishi, Panasonic, Philips, Pioneer, Samsung, Sharp, Sony, Yamaha and Zenith.

Customers in the USA have been waiting for the blu ray recorders for quite some time now. It is anticipated but has not still come true.  In the first 6 months of 2009, Panasonic, nevertheless, is slated to introduce the first freestanding blu ray recorder in the United States of America. Expectations for blu ray recorders make the market prospective, but blu ray recorders will encounter tough contests from the rest of the available HD recording tools such as the HD-TIVO and Cable/Satellite HD-DVRs. 

Cinema studios and other entertainers are insisting on certain copy-protection obligations to be fulfilled by blu ray recorders.   Further, the price of blu ray recorders, from what we have seen in Japan, is far higher than the price of standalone blu ray players (already introduced in the US) which the US market already perceive to be expensive.  One more thing to be contemplated here is the price of High Definition DVRs.  A blank 25GB BD-R Disc cost about $8-$10 which is relatively cheap as well as convenient.

Despite all the negatives, the introduction of blu ray recorders to the US is a much awaited phenomena.

About Blu Ray Discs

With Help Of: Neoprene PC Adapter Cases. In the early 1980’s, the world changed with the introduction of the CD. 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 enabled widespread recording and distribution of audio.  Anyway, the necessity for greater storage capabilities grew in the nineteen nineties and resulted in the creation of the DVD which saw a five-fold increase of storage capabilities.  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 novel optical disc system is an important creation of the Blu Ray Disc Association (BDA) which includes Dell, Hp, Hitachi, LG, Samsung, Apple, JVC, Panasonic, Mitsubishi, Sony, Pioneer, Philips, Thomson, Sharp and TDK.   The BDA boasts 180 of the world’s leading consumer electronics, media and personal computer manufacturers.

Blu ray discs offer an increase in storage capacity with its 25GB on a single-layer disc to its 50GB on a dual-layer disc. It is the last word in user experience and facilitates rewriting, recording, playback and distribution of HD videos. 

The blu ray discs have been founded on the bare disc physical form factor which makes it compatible with CDs and DVDs.

The blu 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) 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.

Presently supported by some of the world’s leading consumer electronics, personal computer, video game, recording media, and music companies, these new generation blu ray discs have also won the support of Hollywood studios and other smaller studios, some of whom have already announced the release of new movies on blu ray discs.

Blue ray discs are the newest intervention in technological sphere.  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 Blu Ray Disc Association comprises one hundred and eighty of the globe’s frontline PC makers, media and consumer electronics producers.

As the name suggests, the blue ray discs make use of a blue-violet laser to read and write data as opposed to the current technology which uses 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.  Moreover, blue ray discs afford a comprehensive storage capability.  A single-layer blue ray disc could hold twenty-seven GB of data which is in excess of two hours of HD video and thirteen hours of normal video.  The double-layer blue ray disc could hold fifty GB of data which is 4.5 hours of HD video and normal video in excess of twenty hours.

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 boasts of an advanced data transfer rate of thirty-six Mbps over the present-day DVDs that does the data transferring @ ten Mbps.  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.  Anyway, the blue ray discs hope to be introduced in a comprehensive range of formats that is to include –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.

DVDs, lets face it have its days counted. 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. HD video content uses up a considerable amount of hard drive space too.  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. 

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 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. 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 easy on the producers too as they are created by injection-molding procedure on a single 1.1-mm disc in contrast to the traditional injection-molding method on a 0.6 mm (High Definition DVD adopts the same process) which in turn cuts down on the 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.
