Optical recording method, optical reproducing method, and optical reproducing apparatus |
| abstract |
An optical recording method, an optical reproducing method, and an optical reproducing apparatus capable of reproducing digital data with high S / N even when a coaxial hologram recording method is used. By using an optical recording medium capable of forming an absorption grating together with a refractive index grating by light irradiation, and simultaneously irradiating the signal light and the reference light Fourier-transformed so as to focus on the outside of the optical recording medium. A diffraction grating corresponding to the interference fringes between the signal light and the reference light or the interference fringes between the signal lights is formed on the optical recording medium, and the signal light is recorded as a hologram. When the reference light is irradiated as readout light, diffracted light represented by an inverted image of the signal light is generated from the diffraction grating formed on the optical recording medium. By detecting the diffracted light and reversing the image data of the reversed image, the binary digital data held in the signal light can be reproduced with a high S / N. [Selection] Figure 11 |
