Abstract
The CD-R market has grown rapidly since the development of this media in 19 88. In addition, PC applications have continued to demand ever higher recor ding speeds. In order to achieve higher speed recording, it is necessary to reduce thermal interference during the recording process. Higher density r ecording is subject to the same effects of thermal interference as higher s peed recording. To directly compare such thermal effects during recording o n different density disks with different scanning velocities, we introduce a new parameter. Applying this parameter, it can be clearly demonstrated th at thermal interference in higher density digital versatile disc-recordable (DVD-Rs) is approximately equal to that in 4x-speed recording with the low er density CD-R. Today, the possibility of 4x-speed DVD-R recording has alr eady been confirmed. It can thus be concluded that write-once organic recor dable media with a 15 GB capacity per 12 cm diameter disk format is very pr omising, because the thermal effects associated with the 15 GB recordable m edia are shown to be equivalent to those in 4x-speed DVD-R.
