Cd/dvd Media 101

Have you confused recently by the various choices available for blank CDs or DVDs? There are so many abbreviations like CD-R, CD-RW, DVD-R, DVD-RAM, DVR + R, etc. So how do I know which type of CD or DVD is suitable for my use? I will briefly describe the various types of blank CDs and DVDs currently available on the market. for CDs and DVDs, the "R" that is found in CD-R or DVD + /-R stands for recordable. This means that you record information such as photos, files, database etc. Basically anything that can be digitally recorded. These types of CDs or DVDs can be recorded only once. So it is important that you record any data you want transferred to a CD-R/DVD-R in one session. The "RW": the media is rewriteable. You can erase and record data on CD or DVD several times. Think of it as a portable hard drive. The cost of a CD-RW and DVD-RW is more expensive than a normal CD-R/DVD-R One of the greatest confusion arises due to DVD-R/RW and DVD + R / RW. What is the difference? In a nutshell, there is no major difference except the standards created by 2 different organizations. It is important to know whether DVD burner supports them. Most DVD burners support both formats, but make sure you contact the DVD manufacturer or the manual on the types of DVD formats are supported. There is a different DVD format known as DVD-RAM, and it is not as common as the other 2 formats. Again, make sure your DVD manual so you can use this format to check. DVD media is typically up to 4.7 GB of data, while up to 700 MB CD media. As a result, DVD Media usually more expensive than CD media, since more data can contain. There is also a new type of DVD media called dual-layer DVD and can store twice the size of a normal DVD. It is quite expensive at the moment and the most current DVD burners do not support this format. This is a basic explanation of the more common types of CD / DVD media on the market. No matter which media you use, it is important to make sure that your CD or DVD burner support that format.

Dvd Formats - What Do They All Mean?

In the modern market place today, there are many formats for optical storage of digital media, ranging from the venerable CD-ROM, and "super secret compression algorithms" to HD-DVD and BluRay, including the inevitable DVD-R and HD DVD - RW formats. Digital optical media formats have their specifications set by working groups, composed of engineers from various manufacturers that intend to build and sell the hardware, and usually each manufacturer has a kind of technology they have developed that they want included in the specifications. By ensuring that their preferred technology is in the specifications, they get paid a small fee for every single device sold, and the sale of the equipment carried in the hundreds of millions per year any royalties - even a small one - adds up to real money. This makes it possible to get format wars, just like at the beginning of the video cassette recorder, with VHS and Betamax. In fact, the only major media format that is not a format war in recent history, the CD-ROM that his specifications by Sony, which owns most of the patents. When DVDs first came out was hammered, and the possibility of recording films came, the format for recordable DVD media is created - it was the DVD-R. Trying to extend that format into read-write access and opportunities led to two camps, and two formats - the DVD-RW and DVD + RW, the difference between the two specifications literally came down to whose controller chip would be used, in terms of end user performance is no noticeable difference, apart from the fact that some devices had difficulty playing back media made with one or the other of the two formats. Because of the increased compatibility with standard DVD-ROM drives, DVD-RW eventually took a lead, but not the commander of one, Phillips was the first manufacturer to a DVD device that could read and write to both formats RW make their hardware specification became the standard used by the computer field. This format war is about to play again. High Definition TV requires much more information than can be packaged in one DVD, so a high definition DVD drive and the media format must be hammered out, both devices use shorter wavelength lasers, for smaller dots in the register recording media, mostly in the blue-green wavelengths of visible light. These two formats, called HD-DVD and BluRay are only on the market now, and the effect is breathtaking. What will succeed in the market? In all likelihood, the company that will succeed will be one (like Panasonic), a device that can read both formats is. When it comes to the ease of production, HD-DVDs are cheaper for film studios to press, when an extension of the existing CD-pressing techniques, while BluRay offers more storage and a longer shelf life - but is produced by Sony, which costs increased royalties. In the market, it is likely the adult entertainment industry that chooses the winner, since they are the first large volume publishers, they already leaning towards HD-DVD for the format of choice, and there is already a working group working with HD-DVD-RW ... which will probably have another format war erupt, knowing how things have worked in the past.
