ABC DVD drive abbreviations

The number of different formats available in DVD drives can be confusing to someone in the market for one. The list is much longer, but some of the common address formats, we have DVD-ROM, DVD-R, DVD-RW, DVD + R, DVD + RW, DVD-RAM, DVD + R DL and DVD ± RW. Wow! This list of common formats is long enough, it's no wonder he is confused!

What about all the formats?

The reason for various recordable> DVD formats is that no group has the technology and the various groups have chosen to one carrier on another technology. There is no industry standard for producers refer to as the time some consumers have limited options.

The first thing is to be used, including the DVD, which stands for Digital Versatile Disc. Some may argue that the V stands for video, but with the capacity to store video, audio and data files is the most versatileKeywords.

Start with the Basics

A DVD-ROM is the unique address will not be registered. ROM stands for Read Only Memory, and refers to the typical drive can only read DVDs and CDs (all DVD players can read CDs). The Lite-On LTD-163-DO-R has attributes representative of the typical DVD-ROM and DVD has a maximum speed of read 16x CD read speeds of 48x and a maximum.

FirstThe entry into different recordable formats, let's address the basics of what the R and RW for the state, regardless of whether + or - in the middle. R stands for recordable, which means that the disc can be recorded only once. RW stands for rewriteable, which means that the recorded disc more than once, and writes are generally prescribed for 1000 in good condition.

The DVD format was developed by Pioneer -R/-RW, and was the first format compatiblestand-alone DVD players. The group, which promotes the technology is called the DVD Forum, which is an international association of hardware manufacturers, software vendors, content providers and other users with leading members such as Hitachi, Samsung and Toshiba. The DVD has -R/-RW technology is based on CD-RW and used a similar approach to burning discs.

The DVD + R / + RW format is a newer format, on CD-RW technology, and compatible much of the stand-alone DVD players. The R + / + RW technology is not supported by the DVD Forum, and his main support comes from a group called the DVD + RW Alliance. The Alliance is a voluntary group of leading manufacturers of personal computing, optical storage and electronics manufacturers "with members such as Dell, Hewlett Packard, Sony and Philips Electronics.

DVD-RAM is based on the differential PD-RW (Phase)> Drives and actually uses a cartridge to hold the previous media (like its PD-RW). Some cartridges are double-sided DVD-RAM, which makes them ideal for organizations, use as a backup system, so DVD-RAM is usually applications that are commercial, and eventually most users do not always need to use alone, or seen this type of unit. RAM standard DVD format is also supported by the DVD Forum and DVD -R/RW discs. But because of their use of aCartridge (limitation and compatibility), and the scarcity and price of media used, DVD-RAM is in third place, if the technique than DVD + R / + RW and DVD -R/-RW.

The + R / + RW and -R/-RW formats are similar, and the main difference DVD + R technology is the ability to absorb multi-level format (with its new DVD + R DL), DVD-R, where record on one level (not all units of R + are capable of burning dual layer, but not -R drives are). The Plextor PX-504U is an example of a + R / DVD + RW external drives in a single layer + R / + RW format, but can also drive to read discs recorded with a DVD recording R -.

What is DVD ± RW?

DVD ± RW is not actually a proprietary format, but the name given to the operation of both units can -R/-RW and + R / + RW. This type of unit is usually called dual in '> Drive unit (not to be confused with a "double layer), since sizes can write to both R / + RW and + -R/-RW. The Samsung TS-H552 is a DVD ± RW drive capable of reading and writing every format discussed so far and then some. Use the advantages of Layer DVD + R DL (dual) technology available with the + R format so that the appropriate media to store virtually double the 4.37 GB capacity of a typical single-layer disc.

The other important thing,Vista with DVD burners is selecting the right media. Media for DVD-R, DVD-RW, DVD + R and DVD + RW discs can all the same, but are slightly different formats to meet specific registration. The average price for both formats is usually the same with RW discs cost more R media of the two formats. Double-layer media is still expensive, and the only way is for owners of DVD + R DLto increase the advantage of huge capacity. Since the layer of units in the market to increase twice the price of DVD + R DL is expected to decrease with increased average production des DVD (these are often referred to as units), the selective media supported, so make sure choose your media wisely.

DVD in a Nutshell
