Media Technologies for 20 GB Single Layer and 36 GB Dual Layer Phase Change Rewritable Disc “HD DVD-ARW”
Published online by Cambridge University Press: 01 February 2011
Abstract
In an effort to achieve as high a storage capacity as possible on a disc format that is similar to conventional DVD using blue-violet laser, a number of new technologies have been implemented for the phase change rewritable media. The technologies include the ways to meet challenges in obtaining larger signal amplitude for shorter bit lengths and lowering the cross erase for narrower track pitches. Technologies developed for both the single layer and the dual layer discs are discussed.
