摘要： PROBLEM TO BE SOLVED: To provide the manufacturing method of a stamper for manufacturing an optical disk which forms an optical disk having a fine pattern by a new method which is not the improvement of a wavelength and a numerical aperture. SOLUTION: In the stamper, the sensitivity of a resist layer 2 to be formed in an under layer is made smaller than that of a resist layer 3 to be formed in an upper layer and the thickness of the resist layer 3 is made thicker than that of the resist layer 2. Irradiating light which is made to irradiate on the surface of the resist layer 3 reaches the surface of the resist layer 2 while being gradually absorbed by the resist layer 3. Light which enters the resist layer 2 decreases rapidly. In the case of performing exposure, when exposure is performed so that spots of the irradiating light are overlapped with each other as shown in the figure (b), parts from which resist is removed are formed in pitches smaller than the diameter of the spot of the irradiating light.

摘要： PROBLEM TO BE SOLVED: To provide a hologram-recording and reproducing method and device capable of obtaining proper reproduction images, without causing reduction in the data storage capacity of a recording medium, even under conditions where the temperature varies widely.
SOLUTION: A pattern signal (checkered pattern) is superimposed on an image data signal and displayed on an image display surface of an SLM 41, and this image is recorded in a hologram recording medium 43 (S1). The recorded image is reproduced, and the reproduction information is converted to a signal by a two-dimensional imaging element 45 (S2). For each of patterns p1 to p5, FFT operation is applied in each of X direction and Y direction (S3), and the ratio between intensity A (f
1 ) of a basic frequency and intensity A (f
2 ) of a double frequency is calculated (S4). For (A (f
1 )/A (f
2 )); properties having a peak point is calculated (S1 to S6), while a tilt angle (θx, θy) of an FT lens 44 is changed. It is determined whether the positions of the peak points of the patterns p1 to p5 are the same (S7) and the tilt angle (θx, θy) of the FT lens 44 has changed, until the positions of the peak points become the same.
