A Double Layer or "Dual Layer" drive is able to write two layers of data onto a DVD, effectively doubling the storage space. Be sure to purchase DVD-R media that is approved for dual layer use.
Some DVDs are dual-layered, allowing twice the data to be stored on a single disc. The data is written into an extra layer in the disc itself, not on the back. A double layer-drive is a device that allows the reading and, depending on the model, recording of these discs.
yes, the HP 8x External Double-Layer DVD RW/CD-RW Drive take up a lot of memory space
LG 8x Internal Blu-ray Disc/Double-Layer DVD RW/CD-RW Drive uses LightScribe technology.
That is an extremely good computer.
yes, it is easy to install external cd drives such as the LG 8x External USB 2.0 Double-Layer DVD RW/CD-RW Drive.
Possibly with another Hard drive or with a good amount of double sided dual Layer DVD's. Depending on the size of the hard drive. basically you use a backup program.
8X DVD super multi Double Layer Support reads and write DVDs but cant read or write CDs.. DVD-RAM support, notably, is absent (though it can be unofficially enabled on some drive models), and Apple has never offered a proprietary Blu-Ray drive or supported the format.
difference between single layer and double winding
it supports every CD or DVD.
