<P>PROBLEM TO BE SOLVED: To provide an information recording system where a high precision, complicated driving mechanism is made needless, and shift multiple recording can be achieved with a simple constitution. <P>SOLUTION: Regarding a light source device 1 in the information recording system, light emitted from a light source 32 is made incident on a half mirror 34. The light reflected by the half mirror 34 is introduced into a light emission part 33a via a shutter member 37. On the other hand, the light passed through the half mirror 34 is reflected by a reflection mirror 35, and is introduced into a light emission part 33b via a shutter member 37. At this time, by driving each shutter member 37 so as to be ON/OFF by a driving part 38, the emission of the light from each light emission part 33 is controlled, and the emission position of the light emitted from the light source device 1 changes. Since the plurality of light emission parts 33a, 33b are located on a face conjugated with the recording face in a recording medium, by changing the emission position of the light from the light source device 1, while shifting an interference image, its recording on the recording medium is made possible. <P>COPYRIGHT: (C)2007,JPO&INPIT |
