Abstract: PURPOSE:To record a bit of information with high accuracy than ever, by recording interference fringes by projecting beams of light from different directions according to the bit of information to be recorded in one area. CONSTITUTION:On a recording area 12, a main beam of light 15 and a sub beam of light interfer with each other, and form the interference fringes, and are recorded on the recording area 12. In forming the interference fringes, the incident angle of the sub beam of light 16 relative to the main beam of light 15 is varied according to the content of the bit of information to be recorded. In other words, for example, when the sub beam of light exists in a direction of 9 o'clock on the left side of advancing direction with respect to the main beam of light 15 advancing linearly on the optical axis 18 of a lens 11, vertical fringes are formed on the recording area. On the other hand, when the sub beam of light exists in a direction of 6 o'clock on the lower side of the advancing direction with respect to the main beam of light advancing linearly on the optical axis 18 of the lens 11, horizontal fringes are formed on the recording area. Therefore, by changing the incident angle of the sub beam of light relative to the main beam of light, plural pieces of information can be recorded in the recording area of only one bit.
