Patent ID: 7972990

Claim:
A process for recording by drawing lines which are adjacent to each other or are adjacent to each other and overlapping each other into a rewritable recording medium of a non-contact type having a reversible heat sensitive color developing layer disposed on a surface of a substrate by scanning the rewritable recording medium with a laser light wherein the process comprises drawing a first line, and then drawing a second line after the first line has been drawn by controlling the following: (i) a time between starting the drawing of the first line and ending the drawing of the second line, or (ii) a width of an overlapped portion between the first line and the second line, or (iii) a time between starting the drawing of the first line and ending the drawing of the second line and a width of an overlapped portion between the first line and the second line, thereby suppressing discoloration of the recorded lines by interference between heat remaining after the first line has been drawn and heat generated while the second line is drawn, and wherein the laser light is from a YAG laser and an output of the laser light is 2.0 to 3.6 W.
