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 line 2 is drawn after a first line 1 is drawn, the time between the start of drawing 1 and the end of drawing 2 and/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 after 1 has been drawn and heat generated while 2 is 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.

Abstract: A structure formed of a resin material with a built-in recording medium comprising at least a means for rewriting visible information with a laser light in a non-contact manner; a laminate comprising the structure and a method for recording in the non-contact manner using the structure or the laminate are disclosed. The recording and erasing of information in the recording medium can be conducted by irradiation with a laser light from outside. The laser light transmittance in a used wave length range and the visible light transmittance through a portion of the structure from a surface on which the laser light is irradiated to the recording medium are in a specified range. Surface destruction of the recording medium due to laser light on rewriting visible information, decrease in durability during cleaning, damages on the recording medium during transportation and deterioration in the color developing property due to light can be overcome.

The resin layer exhibits uniform transparency at portions the color of which is eliminated and suppresses formation of scratches. The mask film is easily positioned in preparation of great printing plates and good contact is easily attained throughout the entire surface suppressing containment of air between the mask film and the printing plate material.

Abstract: A method for recording information into a rewritable thermal label of a non-contact type by irradiation with a laser beam is provided. When a prescribed drawing is conducted by irradiation with a laser beam focused on the rewritable thermal label of a non-contact type using an optical scanning apparatus, the optical scanning apparatus is driven continuously without activating oscillation for the laser beam, and the drawing is conducted by activating the oscillation for the laser beam and scanning with the laser beam only when a locus of a laser beam which would be emitted if the oscillation for the laser beam would be active (a virtual laser beam) moves at a substantially uniform speed. Damages to the recording face of a recording medium after repeated recording and erasure of information by a non-contact method are decreased, and the recording medium can be used repeatedly 1,000 times or more.
