Blu-ray revolution.


Blu-Ray, or Blu-ray Disc (BD) belongs to the next-generation of optical disc formats which is initiated by the Blu-ray Disc Association (BDA). It is an assemblage of manufacturers belonging to consumer electronics, personal computer and media manufacturers which include names such as Dell, Apple, Hitachi, HP, LG, Panasonic, Philips, Samsung, Sony, Sharp, Thomson etc.

The Blu-ray format was developed in an effort to record, rewrite and playback high-definition video and to enable storing large amount of data. Blu-ray drives for personal computers are the new entrant in the market. These full high-definition writable and rewritable drives supports up to 50 GB of data on BD-R (write once) or BD-RE (Rewritable) discs or can give up to four hours of HD video. These Blu ray driver can burn a full 25 GB disc in around 50 minutes. They can also fit into every optical drive slot in a user’s pc chassis and comes in an array of colors; these drives can fit in any PC and still gives its users optimal results.

The current DVD, DVD+R, DVD+RW rely on a red laser in an effort to read and write data, on the other hand a Blu-Ray Drives use a blue-violet laser instead of red one, that is the reason why they got their name as Blu-ray. One of the main advantages of using blue-violet laser i.e. 405nm is that it contains a shorter wavelength than that of a red laser i.e. 650nm. Blu-ray drives are compatible with even CDS and DVDs as they use BD/DVD/CD attuned optical pickup units. The recent developments enunciated by the manufacturer Pioneer are the proof that now the storage capacity can hold data up to 500GB on a single disc, thus making it a multi-format burner. This large storage capacity is achieved by using 20 layers on the disc.

There are various Blue Ray Drivers manufacturers in the market viz., HP, LG, Sony, Samsung, Panasonic, Sony, Philips and Pioneer. There are a variety of versions of Blu-ray drives available viz., Panasonic SW-4583-CNC7 Blu Ray ROM - DVD+R 16X, DVD+RW 8X, DVD-RW 6X, CD-R 24X, BD-ROM 4X (OEM), Norazza DVDBREXT1 External BLU-RAY ROM Drive, Pioneer BDC-2202B Blu-ray Disc/DVD/CD Combo Drive SATA.

Bluetooth Bluejack

Bluetooth technology operates by using low-power radio waves, communicating on a frequency of 2.45 gigahertz. This special frequency is also known as the ISM band, an open, unlicensed band set aside for industrial, scientific and medical devices. When a number of Bluetooth devices are switched on in the same area, they all share the same ISM band and can locate and communicate with each other, much like a pair of walkies talkies tuned to the same frequency are able to link up. Bluetooth technology users take advantage of this ability to network with other phone and can send text messages or electronic business cards to each other. To send information to another party, the user creates a personal contact name in his or her phone's address book -- the name can be anything from the sender's actual name to a clever nickname. Bluejackers have devised a simple technique to surprise their victims: Instead of creating a legitimate name in the address book, the bluejacker's me
