<P>PROBLEM TO BE SOLVED: To reduce recording positional shift of a laser unit, even if the interval between a plurality of laser units is varied. <P>SOLUTION: A temperature detecting circuit 31 detects the temperature of the vicinity of an optical recording head H, and a control means causes the optical recording head H to move in the sub-scanning direction Y, at a speed higher than the normal feed speed according to the detected temperature. An elongation X is dispersed equally to recording lines L1-L4 of the respective laser channels Ch1-Ch(N) so that the enlarged pitch A+X, between the laser channels corresponds to the normal laser channel pitch A, thereby preventing the generation of gaps F of the recorded images between the recording areas of the respective laser channels Ch1-Ch(N). The optical recording head H is moved in the sub-scanning direction Y at a speed lower than the normal feed speed, and a reduction X is dispersed equally the recording lines L1-L4 by the control means so that the reduced pitch A-X between the laser channels corresponds to the normal laser channel pitch A, thereby an overlap G of the recorded images is diffused, after the final recording line L4 of the recording area of each laser channel Ch1-Ch(N). <P>COPYRIGHT: (C)2009,JPO&INPIT |
