Innovating Storage Devices
For many years, the development of storage devices has been continuously improving quality.
The market is in a state of competition and companies are increasingly trying to adhere to the head. The use of the CD format during 1979, already moved the floppy disk format for a while. Sharing CD-ROM format can 80minutes/700 MB.
Then, the DVD format is very popular, it is capable of much more data, more common single layer DVD 4.7 GB, you can, but double level Double Layer DVD 17 GB recording.
Another device is very useful USB pen drive, which is now largely in the world. This type of device has a storage capacity varies, USB Pen Drive 16 GB may also, but there are also certain that the 128 GB recording. On the market you will find Pen Drive with many forms and colors, they are less heavy and faster CD in the data being transferred.
The latest news on the storage, creation of a new type of DVD, high definition DVD (HD DVD), but its direct competitors, Blu-ray Disc or BD.
The two new formats to video and audio quality more and more defined and detailed to enable the public to discover life even more realistic.
BD has a storage capacity more important. With a blue laser, it is able, up to 54 GB of data, nearly 12 times more than single-layer DVD. This capacity seems huge, but the discs, MPEG-2 to the general rule, producers are limited to two hours of high definition content on a single layer BD-ROM. This has necessitated the creation of Double Layer discs (50 GB), but also new, requiring MPEG-4.
In July 2008 was also announced 16-layer 400GB Blu-ray, but they have not yet marketed.
Today, the fight is won, it is undoubtedly of BD, because in February 2008, Toshiba, which owns the format rights to the opponent, announced that more than not to develop, produce, market or HD-DVD player and recorder, effectively the end of the format war.
Sony’s PlayStation 3 as a catalyst for Blu-ray, the PlayStation 3 with a Blu-ray drive as main storage of information, without the console, consumers continue to buy a BD player, and probably a new TV screen, high definition, to see what type of discs.
There is no doubt an obstacle to the spread in the mass market of this new technology, at least for the first year.
Although all the film’s producers have already announced their support for the BD format and already-released film in this format.
A great doubt on this format only if it able to lower production costs and thus prices down to the final consumer.
So far, it seems that the discs cost more or less the same as normal DVDs. The real problem is that until today the sale of BD player is much lower than expected. This is because consumers believe that the common DVD quality is already bad enough, the price of the BD player is still too high and that consumers would perceive as overwhelming, the improvements in video and audio quality to justify the purchase of this new device. And until today, nobody can say they are wrong.
