DVD R is short for DVD Recordable, a technology that works similar to the CD R. The first thing to understand about DVD R is that this you can record data only once on a disk. Once written, the data becomes permanent.

When you work on the computer, you probably find it very convenient to store data on the hard drive. There is enough memory space, and you feel the stored data is safe. But computers, in a way, have a mind of their own. If they should crash, all of your data will be lost. This is where the DVD R comes into the picture, because you can easily make a back up disk of your work. This is possible because of the recording ability of these DVDs.

The added bonus about DVD-Rs is that they are comparatively inexpensive. If you search the net, you will come across many companies offering attractive bargains and discounts on bulk purchases. Normal pricing for blank DVD-R disks range from $10 to $25.

But, don't be carried away by a bargain. The market is flooded with fake DVD-R disks. In most cases, the consumer is never actually sure of the quality of the disks he is buying. Even the name of a brand printed on these disks cannot guarantee the quality. This is because the brand does not actually tell you anything about the manufacturer.

The best way to shop for these disks is by trial and error.

Search the market and you will find that they are available for as little as $1. Buying in bulk, you will find that your DVD player may not recognize all of the disks. Again, the best way to shop for them is by trial and error. The most recommended names in the current market include Sony, Verbatim and Maxell.
