subject: Finding Out More About Dvd Rw [print this page] There are many different technological terms that we hear nowadays; and although we all love the advancements in technology for some people, it will be a bit difficult to recognize what these terms stand for. Take DVD RW and HD DVD Drive for example. Even though many people would know exactly what these terms stand for, some people could be clueless.
DVD RW
Let's spend some time to talk about DVD RW. DVD RW stands for DVD rewritable, which is a re-recordable DVD format which is similar to DVD RW or CD RW. The data on this kind of disc can be erased and recorded over numerous times without damaging the medium. If you know that you will need to use the recording space more than once, it will definitely be worth it for you to purchase a DVD RW disc.
DVD RWs are rewritable optical discs with equal storage capacity to a DVD R, typically about 4.7 GB. The format was actually developed by Pioneer in November 1999 and has exploded in popularity since then. The advantage is held by these discs over the standard DVD R discs is that they offer the ability to erase and rewrite to a DVD RW disc. They are thus well worth the money and you can continue using them over and over again, whereas with the common DVD R disc you are unable to do this.
It will depend on what you will be planning to save on the disc which can decide whether you really want a DVD RW disc or not. As an example if you are planning on transferring important data for business reasons which will be permanent, you are able to stick with a DVD R disc; whereas if you are going to be putting music on that you might want to change you should probably stick to the rewritable disc. You will notice immediately just how much easier it becomes shopping for something after you are actually aware of what it is and the technology that it presents me.
The recording layer in these discs is not an organic dye but rather a particular phase change metal alloy which is often GeSbTe. The alloy can be switched back and forth between a crystalline phase and an amorphous phase. There is also now an even newer format known as the DVD RW2, and older DVD burners are not all forward suitable for this new standard, thus you will have to know about this.
