Optical storage products are to be erased, continue to develop the direction of large capacity, and has a great capacity DVD discs, CD-R and is undoubtedly an ideal choice for CD-RW after the following. Precisely because of this, the current foreign vendors are vigorously develop rewritable DVD technology. For now, DVD discs There are four major mainstream recording format.
1, DVD-R (DVD Recordable) format
Data written to DVD-R format can not be modified after, it is also known as a write-once format DVD burner. DVD-R disc to burn burn principle and the principle is similar to CD-R, is the use of a laser to write data on the dye layer, for DVD-ROM drive to read, you can play DVD-Video player. Now the DVD-R format, there are two: DVD-R (G) and DVD-R (A), except that a different wavelength of the recording laser. DVD-R (G) using a 650nm laser, and DVD-R (A) using a 635 nm wavelength laser. DVD-R (G) mainly for home and office users to record discontinuous archive, and uses a copy protection technology, uniform standards established by the DVD Forum in 2000. The DVD-R (A) is in the vanguard in 1998 when first proposed.
2, DVD-RAM (DVD Random Acess Meory) format
DVD-RAM is Japan's Hitachi,Panasonic a rewritable DVD, led by Toshiba Group has developed, it got the DVD Forum (DVD format and support a definition of industry groups) support, mainly divided into two types of computers dedicated and dedicated appliances. Burn principle and CD-RW, as also uses phase-change technology. DVD-RAM burner somewhat similar MO drive, DVD-RAM disc has a clip-on protective shell, so DVD-ROM drives and DVD players on the market can not be read. The biggest advantage of DVD-RAM disc can rewrite more than 10 million times, ranking first in all rewritable recording medium. Standard DVD-RAM disc capacity of single-layer formulation of early 1998, only 2 .6GB, double 5.2GB. After 1999 to a single layer 4.7GB, double capacity in 2000 was changed to 9. 4GB. But the disadvantage is also a lot of DVD-RAM, DVD-RAM discs brittle, difficult to maintain the integrity of the data can not be used on DVD players or DVD-ROM drive.
3, DVD-RW (DVD Rerecordable) format
DVD-RW specification is led by the pioneer, DVD Forum in November 1999 to complete the development of version 1.0 specifications, and to develop complete version 1.1 of the specification in 2000. DVD-RW products targeted at consumer electronics products, mainly to provide similar functionality over VHS tapes, for consumers to record high-quality audio and video multimedia data. However, DVD-RW functionality also applies to the computer, Apple and Compaq will be DVD-RW drive as a mass storage device. DVD-RW are the advantages of compatibility, it is the development of the earliest repetitive recording medium can be used to store video, audio, and other data, and most DVD -ROM drive can be a good read DVD-RW discs . The initial DVD-RW burner can not burn a CD-R and CD-RW discs, but recent support these formats DVD-RW burner drive debut, the drawback is a slower burn.
4, DVD+RW (DVD ReWritable) format
DVD+RW specification is dominated by DVD alliance, is not part of the formal specification of the DVD Forum, Microsoft has expressed clear support for DVD + RW in the next generation operating system. DVD+RW products while positioning in consumer electronics products and computer storage products. DVD+RW is an extension of the DVD standard, compared with other DVD recording formats, its compatibility is the highest of several burning in existing formats. DVD+RW discs using phase change material, its reflectivity with bunk same read-only DVD disc reflectance, thus eliminating the DVD+RW DVD-ROM drive reads data of the problem difficult. DVD+RW drive features a very comprehensive, write faster, you can read DVD-R / DVD-RW discs, but can not burn a DVD-RAM / DVD-RW discs. Number of rewrites to DVD+RW provides approximately 1000 times, can help you complete the video, audio, and data storage.
