Digital Video Disks or DVD as they are commonly known is a storage device that is used to store audio, video or data. Blank DVD is inserted in a DVD recorder and the desired media or data is recorded with the help of a laser ray. DVD blank discs generally have a storage capacity of approximately 4.7 Gigabyte. Due to this increased storage space; DVDs are generally preferred by individuals over CDs.
There are different formats of blank DVD available in the market. The earliest one to be introduced was a DVD – R, which is pronounced as ‘DVD minus R’. These discs can only be used once to record data. This means that once something is recorded, it cannot be edited or deleted.
Another format of DVD blank discs is DVD + R, pronounced as ‘DVD plus R’. These are of a slightly better quality than DVD minus R and are also a one time recordable disc. A modified version of these two discs is the DVD RW i.e. DVDs that can be re-recorded a number of times.
One of the most recent developments in the world of DVDs is the introduction of blank DVD dual layer. As the name suggests, these DVDs have two layers of storage capacity in them. Thus the total storage capacity of a blank DVD dual layer is approximately twice than that of a normal DVD. With a capacity of 8.54 Gigabyte, these DVDs can be used to store more data and media than any other disc. Moreover, both layers of a dual layer disc can be played one after the other, with a minimum time gap between them, thus proving ideal to store movies, video clips or any audio media.
The advantage of a blank DVD dual layer is that it is fully compatible with normal DVD players, thus there is no need to change the player to avail the benefits of this new technology. Even recording on these dual layer DVDs can be done with the help of present DVD R recorders. However there may be some exceptions and a few DVD recorders might not be able to record on these dual layered discs.
Blank DVD discs have a disadvantage that even a minor scratch on its surface can affect its quality of working or even make it useless. But advancement in technology and the introduction of products like dual layer discs and blue ray discs have take care of all these problems and made DVDs a safe storage device for people’s precious data.
