Filed: 1988-12-15
Abstract: PURPOSE: To read out clear type face codes formed on an optical recording medium automatically at high rate with high reliability by an arrangement wherein a light receiving unit receives only a diffracted light having diffraction order different from zero order. CONSTITUTION: A scanning beam from a light source 10 having wavelength in narrow band irradiates the code region 20 on a compact disc 18 through a condenser lens 12. Reflected light from the code region 20 is sent through an objective lens 14 to a light receiving unit 16 functioning as a photodetector. The objective lens 14 receives only-1st order diffracted light. Zero order diffracted light B is not reflected on the compact disc 18 toward the objective lens 14. Clear type face codes having optical phase lattice structure comprising numerals, characters and symbols are recorded in the code region 20. Since the characteristics of optical phase lattice are utilized in the irradiation with light, an ideal optical contrast is obtained between the type face code and background, i.e., the surface of compact disc 18.
