<p><P>PROBLEM TO BE SOLVED: To prevent a recorded position on a recording medium from being shifted even when a recording medium holding means is eccentric or the recording medium held thereby is floated. <P>SOLUTION: In this recorder, a recording medium 1 on which the recording is performed by exposure to light is held by the rotatable recording medium holding means 2 and the recording medium 1 is exposed by a plurality of recording means 8 arranged in the width direction of the recording medium 1, and then the recording is performed on the recording medium 1. The recording means 8 are provided so as to expose the recording medium 1 from a position diagonal with respect to a normal line direction of a circumferential face of the recording medium 1. A distance between the recording means 8 and the recording medium 1 held by the recording medium holding means 2 is detected by means of a distance detecting means 16, and then an exposure start timing of the recording means 8 is adjusted according to the detected result. As a result, it is possible to prevent the recorded position on the recording medium 1 from being shifted even when the distance between the recording means 8 and the recording medium 1 is varied. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
