Abstract

Under current CD-R and CD-RW technology, whenever a present mark is burned onto a CD, only the dimension of the present mark is considered in controlling the heat source (e.g. a laser). The present invention improves upon the current technology by taking into account not only the dimension of the present mark but also the effects on the present mark due to the marks and spaces within relatively close proximity to the present mark. By doing so, the present invention significantly improves the accuracy of the writing process. This in turn enables the present invention to eliminate the writing errors of the prior art.
