DVD-R, which has a capacity of 4.7GB, was developed using thermal design technology extended from CD-R. The quality of recording on DVD-R is governed mainly by thermal accumulation and diffusion in the layers, which causes interference that restricts the recording density and recording speed. In an attempt to reduce thermal interference and extend the range of recording speed from IX to 4X, we carried out both theoretical and experimental simulations. This paper describes the results of actual IX- and 2x-speed recordings and discusses the possibility of 4X-speed recording.
