Double Layer disc, with a matt silver surface. Double Layer DVDs provide a massive 8.5GB (2.6 for 8cm products) storage capacity. The double layer of recording has been made possible by the creation of a new substrate layer that sits in between each recording layer, that allows the laser beam to record on both layers. Once the first layer has been recorded, the laser re-focused to record on the second layer.
