Pressed DVDs are what you find at your local video shop. They will work in over 99.9% of DVD players and computer DVD ROM drives. However, due to the large price of glass mastering, we usually only press DVDs for large runs (1000 minimum). These include: For small runs we use recordable DVDs. This category includes single write formats (DVD-R including DVD-R DL, DVD+R) and multi write formats(DVD-RW, DVD+RW, DVD-RAM). Each format has limited compatibility.

There are three recordable versions of DVD-ROM: DVD-R, DVD-RAM, and DVD-RW. DVD-R can record data once (sequentally only), while DVD-RAM and DVD-RW can be rewritten hundreds of thousands of times. Final versions of the DVD-R and DVD-RAM specifications were published in August 1997 (see 6.1). DVD-RW will be finalized by the end of 1998. These recordable media are not currently usable for home video recording (see 1.14), though home DVD-RAM recorders will eventually become available.

Both DVD-R and DVD-RW types generally come in the single-sided, single layer 4.7 GB capacity, which is roughly equal to 120-minutes of standard playing time. You can also now find 9.4 GB double-sided discs entering the market, although there are no players which will automatically play both sides of the disc without ejecting it and turning it over. Eventually, there will be DVD-R discs available that will hold around 20 GB of data, recorded into two layers on each side of the disc.

DVD-RAM uses Zone Constant Linear Velocity (also known as Z-CLV) for reading. It divides the disc into several districts and arranges in a spiral way. Each district contains several sectors. Each sector has its own physical address. Therefore, it uses the same "Data Random Storage" as HDD, which also provides burning repetition. Its burning principle is similar to CD-R / RW, which uses Constant Linear Velocity (also known as CLV). A DVD-R can only be burned once.

DVD-R was the first DVD recording format released, and it is compatible with most DVD players. DVD+R is a newer format (introduced in early 2002), and it has some additional features such as lossless linking, CAV, and CLV writing. DVD+R is compatible with most newer DVD players (about 88% of all DVD players). DVD-RW and DVD+RW are essentially the same as above, except with DVD-R and DVD+R media you write to it once, and with DVD-RW and DVD+RW media you can erase and rewrite many times.

There are many different capacities of DVD. The one used by consumer DVD burners is a DVD-5. It has one side and one layer- making its total capacity about 4.2 GB. When we say layer we mean that a DVD surface can actually have two slightly different layers that can be read by the player's laser. In general, most Hollywood DVDs are DVD-9s: one side, two layers with a total capacity of 8.4 GB.

DVD+R is a non-rewritable format and it is compatible with about 89% of all DVD Players and most DVD-ROMs. DVD+RW is...

DVD+RW disc For Data' is a disc primarily used for writing in a DVD+RW drive or DVD+RW/+R drive installed in a PC. DVD+RW disc for Video' is a disc primarily used for recording on a personal video recorder that supports DVD+RW media. DVD+R disc for Video' is also primarily used for recording on a personal video recorder that supports DVD+R media. But, actually, there is no difference between 'DVD+RW for Data' and 'DVD+RW for Video' discs, or between 'DVD+R for Data' and 'DVD+R for Video' discs.

Nothing. This FAQ is about CD-R and CD-RW, and only crosses over into DVD when the two technologies rub up against each other.

You cannot record on DVD-RAM using a CD-R/CD-RW recorder; you need a dedicated DVD-RAM recorder and authoring application.

The EVERPLAY founders have designed the standard so that it is media independent. This gives the consumer the flexibility and choice, while allowing for the survival of the standard as media types eventually change. MPV is a broad standard developed by an association that produce purely technical standards. The MPV developers encourage its use in development of practical standards by other companies.

quot;For Data" disc are used for burning "Data". "For Video" disc is used for burning "Films". Basically there are no specific differences between the two, but it is recommended that you use "For Data" discs for burning "Data", and "For Video" for burning "Films".

DVD+R/+RW is designed from the start to be compatible with existing DVD-ROM drives and DVD-Video players, both on a physical as well as on a logical level. This means that a DVD+R or DVD+RW disc recorded in a DVD+R/+RW video recorder can be played in virtually all DVD-Video players or DVD-ROM equiped PCs, and that any DVD+R or DVD+RW disc recorded with data on a PC DVD+R/+RW drive can be read by most DVD-ROM drives. click here to visit DVDPLUSRW.org for more information about this format
