Abstract

A thermally balanced write strategy has been developed for high-speed recording of CD-recordable (CD-R). It is adopted in the recent multi-speed CD-R standard as the media testing condition. The write strategy accounts for the effects of thermal interference and heat accumulation during the recording process. Detailed thermal calculations of the resulting pit shapes and sizes support the approach. CD-R recording speeds of up to 40X are demonstrated using this Thermally Balanced Write Strategy.
