Understanding DVD Drives And How They Work

DVD drives have played a very important role in the development of data storage technology. Basically, the high-capacity DVD drive is a piece of simple equipment that is used to read and write data on DVD disks. In older times and even today, almost all computers and laptops are supplied with an internal DVD drive, however, there are also a lot of external DVD drives available to provide more portability.

The operating method behind computer-compatible DVD drives is very easy to understand. Basically, all DVD drives use a laser to read and write data on the disks. When a user sends a request to write data on the disks, the drive uses a red laser to create microscopic pits on the surface of the DVD disks. The pattern of these small pits on the disks represents the data. Similarly, when the user sends a request to read the data from a DVD disk, the laser shines on the surface and reads the reflected light to decrypt the data.

Widely Available Types of Compatible DVD Drives

As discussed above, DVD drives can be classified into two major categories, internal drives, and external DVD drives. But this is a board-level distinction, and when classified on the basis of operating features computer-compatible DVD drives can be differentiated into the following two main types, the DVD-ROM, and the DVD+RW devices.

The DVD-ROM readers are the older version and can only be used to read the disks. On the other hand, the DVD+RW devices were created to increase the functionality of domestic computers, to enable them to read and as well as write data on blank DVD disks.
