Happy Reading :)

Tech format battles have been brewing for decades. Over the years it has played out across various formats for example, AC versus DC, VHS versus beta, CD versus DVD and the list goes on...usually it’s a bloody war over millions or even billions of dollars. The most recent fight being the HD DVD Blu-ray war in which Sony and Toshiba fought it out. Toshiba lost with a little help from the trojan horse PS3.  

Blu-ray was the name derived from the underlying technology which utilizes a violet-blue laser to read and write the data. The name is a combination of blue violet laser and ray optical beam.  The spelling of Blu-ray was no mistake.  The e in blue was intentionally left out, in order for the term to be registered as a trademark.

Slowly, but surely the Blu-ray disc is replacing the conventional DVD much like the latter did to VHS tapes. Luckily, almost all of the major manufacturers, created a group consensus panel to get on the same page, it’s called the BDA (Blu-ray Disc Association). The BDA has stated that all Blu-ray players will play DVDs. The BDA expects every device to be backward compatible with DVDs and all current game players xbox, ps3, and wii are all Blu-ray compatible. VHS, which has virtually disappeared in the marketplace did not have this advantage to prolong it’s life, the standard DVD will probably last for several more years because they can indeed be played in Blu-ray players.  Plus, standard DVDs are very inexpensive to produce, which may be perfect for video productions that do not require high definition.

Just as DVDs meant a 7 time increase in storage capacity compared to the old CDs, Blu-rays hold about 7 times the information of a DVD. The standard Blu-ray disc will hold 25GB of information per layer. Currently there are single, dual, triple and quadruple layers of Blu-ray discs that are available. The triple and quadruple are for re-writer drives and they hold 100GB and 128GB respectively. Blu-ray discs are primarily used for feature films, TV shows and video games, such as the Playstation and Xbox series. So how much video can fit on a Blu-ray disc? Well over 9 hours of high-definition video can fit on the 50GB disk and about 23 hours of standard definition video. Blu-ray discs will increase DVD capacity by 5-10 times due to that simple change in the lasers color.  Basically the blue laser is sharper and more focused as opposed to the red laser that was utilized to burn DVDs. Therefore, it can hold higher density information due to the fact that Blu-ray is placed closer to the disc and is sharper. A standard DVD can hold just over 4GB of information while the Blu-ray can hold up to 128GB if the quadruple layer disc is used. Even the standard single layer Blu-ray can hold over six times the information at 25GB. What’s tech mumbo jumbo all really mean? The bottom line is that the increased storage can hold more picture detail, HD audio, and information that can drastically improve the users experience.

We get the question in our Denver electronics store quite often, “Will Blu-ray replace DVDs?”  the simple short answer is “yes”.  At least that's the expectation. Blu-ray format has received the product support for major movie studios.  First Paramount went blue, then they dropped off like flies and finally, Warner Brothers dropped hdtv/dvd all together.  Fox, Disney, Sony, Lionsgate, and MGM have all released titles in the Blu-ray format.
