What DVD formats are recordable?

This article will give you basic knowledge of six DVD format, and tells you the difference, which are recordable, how to get DVD video playable without limitation.

What format does your burner require? DVD+R, DVD+R DL, DVD-R, DVD+RW, DVD-RW, or DVD-RAM?


DVD-R Media: A write-once, recordable format. DVD-R drives can write DVD-R discs, which can be written to only once, as opposed to a DVD-RW drive, which can write and rewrite to RW media multiple times. The Authoring Use Drive (635nm Laser) was introduced in 1998 by Pioneer, and the General Use Format (650nm Laser) was authorized in 2000. DVD-R offers a write-once, read-many storage format akin to CD-R and is used to master DVD-Video and DVD-ROM discs.

DVD-RW Media: DVD ReWritable. A rewritable DVD format that is similar to DVD+RW, but its capability to work as a random access device is not as good as that of the +RW. DVD-RW has a read-write capacity of 4.7 GB.

DVD+R Media: Short for DVD+Recordable, a recordable DVD format similar to a CD-R. A DVD+R can only record data once and then the data becomes permanent on the disc. The disc can not be recorded onto a second time. DVD+R and DVD+RW formats are supported by Philips, Sony, Hewlett-Packard, Dell, Ricoh, Yamaha and others.

DVD+RW Media: The DVD Plus RW Alliance is a group of companies that includes Philips and Sony. They propose standards for recordable and rewritable DVDs.

DVD+R Dual Layer / Double Layer Media: Double Layer DVD+R media has an amazing 8.5GB of storage capacity. This incredible capacity is enough for up to 4 hours of DVD quality video, 16 hours of VHS quality video or over 120 hours of MP3 audio. Compatible with all current DVD video players and DVD-ROM drives as well as new DVD+R DL drives, the disc is ideal for virtually any business or household application.

Dual-layer DVD-R media offers genuine advantage over the current single layer 4.7GB DVD. The new dual-layer recordable DVD-R disc allows users to read, write or view almost twice the amount of data that is currently possible with the single layer. The advanced technology means that material can be read or recorded on one layer without affecting the other. There's no need to flip sides or change discs.

DVD-RAM Media: DVD Random Access Memory is a rewritable DVD disc endorsed by Panasonic, Hitachi and Toshiba. It is a cartridge-based, and more recently, bare disc technology for data recording and playback. DVD-RAM bare discs are fragile and do not guarantee data integrity. The first DVD-RAM drives had a capacity of 2.6GB (single-sided) or 5.2GB (double-sided). DVD-RAM Version 2 discs have double-sided 9.4GB discs. DVD-RAM drives typically read DVD-Video, DVD-ROM and CD media. The current installed base of DVD-ROM drives and DVD-Video players cannot read DVD-RAM media.


When choosing a format to use, note that DVD-R/RW won’t record in a DVD+R/RW recorder or burner, and vice-versa. This is not an issue when using a Multi-Format recorder or burner, and most DVD players and DVD-ROM drives will read either format.

What is DVD and Why DVD is Popular

DVD is an optical disc technology with a 4.7 gigabyte storage capacity on a single-sided, one-layered disk, which is enough for a 133-minute movie. DVDs can be single- or double-sided, and can have two layers on each side; a double-sided, two-layered DVD will hold up to 17 gigabytes of video, audio, or other information. This compares to 650 megabytes (.65 gigabyte) of storage for a CD-ROM disk.
 

DVD uses the MPEG-2 file and compression standard. MPEG-2 images have four times the resolution of MPEG-1 images and can be delivered at 60 interlaced fields per second where two fields constitute one image frame. (MPEG-1 can deliver 30 noninterlaced frames per second.) Audio quality on DVD is comparable to that of current audio compact discs.

Formats:

  • DVD-Video is the format designed for full-length movies that work with your television set.
  • DVD-ROM is the type of drive and disc for use on computers. The DVD drive will usually also play regular CD-ROM discs and DVD-Video disks.
  • DVD-RAM is the writeable version.
  • DVD-Audio is a CD-replacement format.
  • There are a number of recordable DVD formats, including DVD-R for General, DVD-R for Authoring, DVD-RAM, DVD-RW, DVD+RW, and DVD+R.

DVD was originally said to stand for digital video disc, and later for digital versatile disc. With the coming of 2014, new DVD releases never take a breather, and even the shortest month of the year will have plenty of popular or critically acclaimed movies that screened in theaters last year hit the retail market.

Since DVD is more and more popular nowadays,  DVD-related multimedia software is plays more and more important role in our daily life. Here, Pavtube DVDAid is my first choice because it converts all my DVD for playing in a more convenient way without bothering to carry the DVDs. Pavtube determines the correct format/file and combines for main movie automatically. Great! Easy!

And besides that, with the Pavtube new official website being released, there are more new money saving software bundles like: DVDAid($35) + DVD Creator($35) = Only $35.9, Save $34.1, which means you can rip DVD to portable devices for on-the-go DVD movie enjoyment as well as get all your video files into playable DVD for entertainment. Really wonderful enjoyment!
