HD DVDs or High definition DVD is on longer available as Blu ray Disc has replaced them all. For writing on DVD, red color laser beam is used, the wave length of which is in the range of 650 nm. Since it uses 650 nm wavelength light, it allows for a more precise etching on the surface, thus compressing the data more and increasing the recording capacity. .

DVD-R and DVD+R can only record data once and then it can only be read but not written. Single layer DVD has recording space of about 4.7 GB. The other type of disc is dual layer DVD. Dual Layer is a technology which permits 8.5 GB storing space on DVD+R disc. With Dual Layer (DL) technology, two recordable layers are obtained on a single sided DVD disc. For this type of recording, Dual layer DVD enabled burner and dual layer DVD media should be used. Dual layer is also referred to as double layer and it is written as DVD+R DL and DVD-R DL on the DVD media. The recording speed of dual layer media is lower than those offered by single layer media. DVD-RW, DVD+RW, DVD-RAM are re- writeable. You can record and erase the data any number of times on these discs.
