Abstract
A system control unit writes image data received from a host apparatus into a first storage regions. Next, the system control unit produces duplication data from the image data written in the first storage region, and then, writes these produced duplication data into a second storage regions. Furthermore, the system control unit furthermore produces duplication data from the image data written in the second storage region, and writes these produced duplication data into a third storage region. As a result, 1 piece of the image data and 2 pieces of the duplication data can be prepared on a buffer memory. The optical disk drawing apparatus draws an image on a drawing layer of an optical disk by employing these image data and duplication data.
