The DVD Media

DVD Optical Drive, as the price becomes more affordable now, this makes us more confused in choosing the type of drive and media (Blank DVD). For instance, there are several types of DVD media available, such as DVD-R, DVD+R, DVD-RW, DVD+RW and DVD-RAM. With these DVD media, we cannot only write/record large files like videos, but also back-up our hard drive efficiently. However before we decide to buy, there are the differences among these standard DVD media that we need to know.
DVD-R
The same as CD-R, this disk can be written once (with a 4.7 GB capacity). There are two types of DVD-R media: DVD-RA (for Authoring) and DVD-RG (for General). DVD-RA is intended for commercial and professional development (such as movies or songs recording) and uses a DVD-RA Drive with 635-nm laser to record. Meanwhile, DVD-RG is the option for home use. It is more affordable than the DVD-RA and available in many stationary stores. This media can also be run on the DVD-RAM and DVD+R unit.
DVD-RW
This is the erasable version of the DVD-R. To use this media, you need to buy DVD-RW Drive. DVD-RW drives can write DVD-R, DVD-RW, CD-R, and CD-RW discs. The same as DVD-R, DVD-RW disks are playable in many DVD drives and players. We can write a large number of data at once. And if we want to write new data on the same disk, we can erase the existing data by formatting the disk. DVD-RW discs can be rewritten about 1,000 times. Read the rest of this entry »
