Abstract
In a process for recording into a rewritable recording medium of a non-contact type, when adjacent lines or adjacent overlapping lines are drawn by scanning the medium having a reversible heat sensitive color developing layer on a substrate with laser light and a second lineis drawn after a first lineis drawn, the time between the start of drawingand the end of drawingand/or the width of the overlapped portion r is controlled as the means for suppressing discoloration of the recorded lines by interference between heat remaining afterhas been drawn and heat generated whileis drawn. When characters, bar codes, solid images or figures are drawn into a rewritable recording medium of the non-contact type by scanning with laser light, excellent readability and visibility of the bar codes can be obtained in recording a plurality of line elements.
