Popis:	The demand for digital versatile disc-recordable (DVD-R) is currently undergoing explosive growth and both higher speed recording and higher density are required. This paper examines the potential for achieving 4x-speed recording on 4.7 GB DVD-R media. 1x-speed and 2x-speed recording are examined experimentally and by computer simulation, and actual recorded signals are found to be in good agreement with predictions based on computer simulation of thermal interference profiles. Based on these results, the heat design technology needed to realize high speed recording is identified and the potential for 4x-speed recording is demonstrated theoretically.
