Sony DRU-700A Writes On 8.5 GB DVDs
Sony DRU-700A: The first internal DVD burner with double-layer support for a storage capacity of 8.5 GB
Sony has come out with a double-layer DVD drive, the DRU-700A, as well as an external version, the DRX-700UL. How do they work? Through different wavelengths of the laser, the data can be stored on two levels. Considering that each blank DVD gives you a storage capacity of 8.5 GB, these DVD burners are ideal for storing large amounts of data or videos. The first double-layer DVDs are now available, and they are set to cost a little more than twice as much as the regular single discs.
