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. Maxell Double Layer Discs provide a massive 8.5GB storage capacity. * DVD+R DL 8.5GB * recordable speed: 8x speed * in Cakebox x10
