Abstract
The present invention provides a pattern drawing device that enables drawing with reduced operational processing loading of the associated CPU. Thus, in a pattern drawing device for forming a plurality of tracks disposed concentrically on a substrate to produce a two-dimensional pattern, a basic pixel sequence is prepared and used repeatedly in forward (positive) and/or reverse (negative) order to produce symmetric portions of the two-dimensional pattern.
