<P>PROBLEM TO BE SOLVED: To prevent increase in the period for image forming in a recording medium with increase in a drawing area even when a plurality of drawing areas are formed in the recording medium. <P>SOLUTION: In the laser exposure apparatus 100, alignment marks on a substrate material 102 mounted on an exposure stage 108 moving in the opposite direction to the scanning direction are read out by CCD cameras 124, 146, 128 mounted on a supporting gate 122, and then the drawing area the position of which is determined by the alignment mark is exposed to the laser beam from a laser scanner. The measured distance from the CCD cameras 124, 126, 128 to the laser scanner 134 along the scanning direction S is specified to be equal to or longer than the pitch of the alignment marks disposed as responding to the top end and the rear end of the plotting region on the substrate material 102. <P>COPYRIGHT: (C)2004,JPO |
