| DVD-R Vs DVD+R |
 | There are two competing formats for recordable DVD. Both can be used for the same purpose i.e. for recording from the television & backing up data. The important thing to understand is that the type of DVD R you buy is determined by the model of DVD recorder you use. Set top DVD recorders tend to be either DVD+R or DVD-R. Philips, and Sony set top recorders use DVD+R, Panasonic and Pioneer set top recorders use DVD-R. The DVD recorder in your computer may use DVD-R, DVD+R or both or even DVD-RAM (please See DVD-RAM section). Historically DVD-R was the first write once recordable format. It was approved by the DVD-Forum in 1998, and Pioneer did much of the development work. Later, in 2001, the DVD+R format was announced by a consortium of electronics manufacturers (Philips, Sony, Yamaha, to name a few); these companies called themselves the ‘DVD+RW alliance’. The reason there are two formats, is that the two groups dislike paying royalties for using each others technology. Unlike VHS Vs Betamax in the 1980s this is unlikely to result in useless recorders as in time most recorders will be able to record in both formats. But for now, Do Not Buy DVD+Rs when you have a DVD-R recorder and vice versa, as they will not work. Finally as DVD-R is the DVD-Forum approved Specification, this disc can be used as a master for DVD manufacturing. |

 | A DVD-R disc is a write once DVD that has a data capacity of up to 4.7billion bytes or 240 minutes recording time dependant on the quality setting you use on your DVD Recorder. A DVD-R is highly compatible with DVD players as it reflects more light than a DVD RW disc. A DVD-R disc is suitable for Archiving data, recording your favourite television program, and for distributing many copies thereof. Depending on the brand, the archival life may be upto and beyond 100 years.
