Title: Optical recorder
Inventor: KAJIWARA TADAYUKI
IPC: G02B26/12
Filed: 1986-07-10
Abstract: PURPOSE:To make the intensity of laser light constant on the surface of a recording body by providing a polygon mirror which varies in reflection factor at right angles to its rotating shaft according to the angle of incidence of light. CONSTITUTION:The polygon mirror 6 is formed by vapor-depositing a metallic layer on the surface and further forming a coating layer of transparent resin thereupon to constant thickness so as to protect the metallic film. This metallic film is thin at a position F where light is incident on the polygon mirror 6 at a small angle of incidence and thick at a position where light is incident at a large angle. Namely, the difference in the loss quantity of energy caused by the difference in the passage distance of the light in the coating layer due to the difference in angle of incidence is corrected by making the reflection factor the metallic film at respective positions. Consequently, the light projected on the surface of the recording body is made constant in intensity, so the superior optical recording device is obtained which is free of variation in the thickness of a line forming characters drawn on the surface of the recording body.
