Understanding DVD Formats

Stack of CDs

DVD technology surely has managed to create a wave all over the world. As soon as DVDs appeared in the scene, people started to wake up to the change in the video quality that these discs had to offer and they immediately got used to it. Besides, who wouldn’t love to watch a movie like Jurassic Park on a DVD?

Thanks to the better video quality that DVDs offer. People always prefer DVDs to the traditional VHS tapes, when having a good time watching movies. However, there has been a sort of revolution in the DVD front too, just as it is seen in case of its predecessor, the VCD. This means just as the VCD can be recorded; the concept of DVD too, is undergoing similar changes.

This simply means that, like VCDs, DVDs too come in a range of formats, namely, DVD+R, DVD+RW, DVD-RW, DVD-R, DVD-RAM and DVD-ROM. Now, thanks to all of these options available. It makes it difficult for the customer to know which DVD to use and most importantly, which DVD will be compatible for their existing system. One question that often seems to trouble people is figuring out the reason for so many DVD formats which have come into existence. In order to clear out any doubts in this matter, the information given below would prove to be ideal in that respect.

One of the main differences usually arises, when we talk about the compatibility and the system that supports the specific type of DVD. These differences are mostly referred to as physical formats of the DVDs. Most of these differences are according to the make of the particular DVD by the different manufacturers. In addition to that, the extensions give the DVDs, i.e., +RW, -RW, -R, +R, etc. which specifies the method of data storage used by the DVD.

Given below are some of the types of DVD formats available. All thanks to its makers like Sony, Yamaha, Dell, HP (Hewlett-Packard), Phillips, Samsung, Toshiba, Hitachi, Panasonic, etc.

DVD R CD Picture

DVD-R - This DVD format allows the user to record any data just like in the case of a recordable CD, i.e., CD-R. The DVD-R format is more useful, when you want to keep some permanent record on the DVD. However, you have to remember that the data once recorded on the DVD-R, it stays in it forever. You even get to buy types of the DVD-R format, i.e., the DVD-RG which is basically for general use and then there is the DVD-RA which is generally used by the authors of the DVD itself. These DVD formats are not available to the public for use.

DVD-RAM - Although these DVD formats may seem to be a little familiar to the common CD-RW, i.e., they can easily be recorded, erased and rerecorded any number of times. However, these DVD formats differ a lot, when it comes to compatibility. This means that the DVD-RAM format is only compatible with the devices that are manufactured by the same company that had made the DVD in the first place. One unique feature of the DVD-RAM is that it looks as if it has been stuffed in some sort of a cartridge.


DVD-RW - Once again, this DVD format works in the same way as the DVD+RW and CD-RW that can be rerecorded till the end. One of the best things about these DVD formats is that the data can be rerecorded and there is no damage done to the medium at all and the DVD format having any -R or even an -RW for an extension, can easily work on any DVD players.

DVD-ROM - This DVD format was perhaps the first of its kind to hit the market in a read only format. That’s why most of these DVDs contain either movies or games. This DVD format has the same attributes as that in a CD, which plays on any DVD-ROM player.

The latest thing to hit the DVD market is the Dual layer technology with companies like Dell, Phillips, Sony, etc supporting this technology. These dual layered DVDs have two layers on one side itself. It is popularly known as the Double Layer DVD by customers who intend to buy one. A double layer disc has the storage capacity of 7.95 GB, whereas a double-sided dual layer DVD can store up to 15.9 GB.

HD-DVD -This simply stands for High Definition DVD and it functions well. It does exactly what it has been named after. The HD-DVD is designed for recording high definition motion picture with the best video quality. One of the best things about the HD-DVD is that its storage capacity is almost four times more than a standard DVD format. Its latest competitors include names like Blu-ray and then the AOD of course.

Blu-Ray Disc - This disc is in an optical disc format, which is designed to store digital data that would include digital video as well as digital music. If compared to the standard DVD, one would find that the former has more storage capacity, i.e., 25 GB in case of single layered disc and 50 GB in case of double layered disc.

All thanks to the memory space of these discs. The 50 GB disc has the capacity of storing up to 9 hours of high definition video and up to 23 hours of standard video format. This technology was developed by Mitsubishi, LG, Hitachi, Sony, Sharp, Phillips, and other companies.

Advanced Optical Disc - These discs are quite similar to the Blu-ray discs. However, they can store about 20 GB on a single layered disc, whereas 30 GB on a double layered disc. The Advanced Optical Disc was jointly designed by the companies, NEC and Toshiba.

Non-Contemporary DVD formats

DVD-MP3 - This DVD is designed in such a way that it only supports digital audio in the MP3 format. This disc cannot be played on all DVD players.
DVD-VCD - This kind of a disc stores data that is encoded with the MPEG-1 format having similar video quality of a standard VCD.

DVD-SVCD - This kind of a disc is not a standardized DVD at all. That’s because the term “DVD-SVCD” is actually used to explain any DVD, which has been hacked into with any data, having SVCD content in the disc.
