Watch Blu-ray movies from the laptop should be good to enjoy, but according to foreign reports, Blu-ray drive could become a heavy burden on the laptop. There are desktop computers equipped with Blu-ray drive, but not as common in the field notebook. In fact, according to analysts, the first generation of Blu-ray drive equipped laptop, there is no way to read the part of Blu-ray movies. Yankee Group analyst Josh Martin said: “Blu-ray notebook’s battery life is obviously the biggest problem,” “If you buy the iPhone, you will find that you endless a two-hour movie, Blu-ray notebook problems with similar.”
Of course, battery life seems to be no way to follow Moore’s Law problems. If the battery life can increase each year some of the notebook should not have to worry about battery life issues. Notebook computer manufacturers hp compaq business notebook 6510b battery now offer Blu-ray drive in the same time, as far as possible to avoid discussion of Blu-ray playback battery life. Under the general test, with the Blu-ray notebook battery time in about 1 hour.
Blu-ray Disc is the next generation optical disc format for DVD discs. Drive is what we usually say the drive, the device reads the disc information. The quality of multimedia in the human requirements of increasingly stringent conditions, to store high-definition video and high-capacity data storage. It is now a competitor HD DVD, the two companies have different support and hope to become standard. Blu-ray’s name comes from its use of the laser wavelength of 405 nm, is just among the blue spectrum, hence the name. (DVD uses 650nm wavelength red light reader, CD is the use of 780nm wavelength)
Blu-ray Disc Association was prepared in January 2006 Consumer Electronics Show product release, and later in the process of R & D Blu-ray technology, Sony considers it necessary to take additional me asures to cope with, then announced the postponement of the release date of PLAYSTATION 3 to November 2006. Blu-ray Disc Association members related to the corresponding Blu-ray technology-related products will be the release date to June 30, 2006.
A single-layer Blu-ray disc capacity of 25 or 22GB, enough to burn a 4-hour high-definition movies. Double up to 46 or 54GB more capacity, enough to burn an up to 8 hours of high definition movies. The capacity of 100 or 200GB, and they are 4 layers and 8 layers. In the current study, said, TDK has announced the development of a capacity of 100GB 4-layer disc. Blu-ray blue laser is used to read files hp compaq business notebook 6735s battery on the disk. Due to shorter wavelength blue light, greater density can read CD-ROM. Why then can read and write Blu-ray discs it even greater density? This talk from the laser:
The laser used to read and write, is a very accurate light, accurate to the limit, is the wavelength of light in general, due to the red wavelength of 700 nm, while the Blu-ray only 400 nanometers, so the blue laser that can actually be more accurate to Only 200nm to read and write a point, in contrast, can only read and write 350nm red laser dot, so the same disc, with many points, and record information more naturally! Blu-Ray Disk is a Blu-ray Disc is the next generation DVD standard, one dominated by Sony and Toshiba, Sony, Panasonic, Philips, as the core, but also get Pioneer, Hitachi, Samsung, LG and other giants of support . Principles for the storage groove recording, to record the traditional trench, but by addressing more advanced tremors achieve greater capacity for storage and data management, the current shock has reached the 100GB. With the traditional form of a CD or DVD storage compared, BD disc is clearly a better reflection rate and storage density, which is its capacity to achieve breakthroughs in the key.
Blu-ray relative to the HD-DVD camp, the original Toshiba has joined the Blu-ray camp, however, the distribution of benefits and related technology features categorically withdraw from the organization to induce Toshiba, NEC turned to joint development of Advanced Optical Disk, and get the DVD-Forum support, renamed HD DVD. As Blu-ray DVD and current DVD format is not compatible with the manufacturer directly increase the transition to Blu-ray DVD production input costs, so much delayed next-generation DVD standard
Blu-ray process.
Jointly by Toshiba and dell inspiron 1720 battery NEC launch of AOD compared to blue laser technology, the biggest advantage is compatible with current DVD, and also the difficulty in producing a DVD than Blu-ray production is much lower degree of difficulty. Blu-ray disc diameter of 12cm, and ordinary compact disc (CD) and digital compact disc (DVD) of the same size. The discs use a blue laser 405n-sided single-layer disc can record, play up to 27GB of video data, than the existing capacity of the DVD more than 5 times (DVD’s capacity is usually 4.7GB), can be recorded 13 hours or 2 hours regular TV high definition TV programs. Blu-ray Disc with MPEG-2 compression technology.
