» What Is DVD-RW? and what is the features of it

DVDRW is a re-writable version of the DVDR. This is a re-recordable format that is similar to the CDRW. This can be rewritten for about 1000 times. It can hold about 4.7 gigabytes of data or video. The content that is written in the disc can be erased and recorded several times without damaging the medium of it. The DVDs created by these devices can be used by most of the DVD-ROM players that are commercial.

Short for DVD-ReWritable, a re-recordable DVD format similar to CD-RW or DVD+RW. The data on a DVD-RW disc can be erased and recorded over numerous times without damaging the medium. DVD-R, DVD-RW and DVD-RAM are supported by Panasonic, Toshiba, Apple Computer, Hitachi, NEC, Pioneer, Samsung and Sharp. These formats are also supported by the DVD Forum.

Consistent with the bickering that had dogged DVD since its inception, the DVD-RAM specification was a compromise between two different proposals by the principal protagonists - the Hitachi, Matsushita Electric and Toshiba grouping and the Sony/Philips alliance - but with primary reliance on that put forward by the former.

DVD, also known as Digital Versatile Disc or Digital Video Disc, is an optical disc storage media format, and was invented and developed by TOSHIBA, and Time Warner in 1995. Its main uses are video and data storage. DVDs are of the same dimensions as compact discs (CDs), but store more than six times as much data.

When DVD technology first appeared in households, users were simply popping DVD discs into their DVD players to watch movies — an attractive option to the then-conventional VCR. But just as compact disc (CD) technology evolved so that users could record and erase and re-record data onto compact discs, the same is now true of DVDs.
