Abstract: PROBLEM TO BE SOLVED: To embody a method for evaluating a stamper capable of much improving the reliability to the quality of an optical disk after molding. SOLUTION: A permeable film consisting of a curable resin having a refractive index equal to or approximate to the refractive index of the base part of the optical disk is laminated and formed on one surface 41A of a stamper 41, which has the rugged patterns 42 meeting recording signals on one surface and is used as a metal mold at the time of forming the light transparent base parts transferred with the rugged patterns of the optical disk, so as to cover rugged patterns 42 and thereafter, the one surface 41A of this stamper 41 is irradiated with a laser beam via a permeable substrate for correction optical aberrations having the refractive index equal to or approximate to the refractive index of the base part of the optical disk and the thickness equal to or approximate to the difference between the thicknesses of the base part and the permeable film in the method for evaluating the stamper which evaluates the stamper 41. As a result, the method of evaluating the stamper capable of exceedingly improving the reliability to the quality of the optical disk after the molding is embodied.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method, for the measurement of the characteristic of a face shape, wherein the characteristic regarding the surface shape of the face, to be measured, of a disk body such as the signal recording face or the like of an optical disk can be measured precisely and efficiently. SOLUTION: The measuring apparatus is provided with a laser Doppler speedometer 11 which detects the speed in the vertical direction of the face, to be measured, of the disk body being turned. The measuring apparatus is provided with an angle-of- inclination calculation part 61 in which an angle of inclination β in the rotation direction with reference to a reference face in each measuring position of the optical disk D is calculated on the basis of a linear speed in each measuring position by the speedometer 11 and on the basis of the detected speed in the vertical direction, The measuring apparatus is provided with a displacement calculation part 60 which calculates a displacement in the vertical direction in each measuring position of the optical disk D. The measuring apparatus is provided with an acceleration calculation part 59 which calculates an acceleration in the vertical direction. The measuring apparatus is provided with a tracking-error-amount calculation part 58 which calculates a tracking error amount which is estimated to be generated in a focus servo system.

Abstract: PROBLEM TO BE SOLVED: To inexpensively make the measurement accuracy of the characteristics of a disk-shaped recording medium high. SOLUTION: A spindle motor 1 for rotating an optical disk is installed so that it can move by a slide motor 5, and a laser Doppler speedometer 6 for measuring the mechanical characteristics of the optical disk is fixed and provided. The speed of a spindle is calculated based on a radius value data that are obtained by converting the output of a potentiometer 9 from analog to digital by an A/D converter 16a and a constant linear velocity data that are inputted via a man-machine interface 20. A sampling rate is obtained based on spindle speed and the (fixed) number of samples during one rotation and a filter coefficient is calculated based on a sampling rate and inputted filter characteristics. Data is sampled from the speedometer 6 at a sampling rate, and digital filtering is made to speed data that is obtained by making conversion from analog to digital by an A/D converter 16b using a calculated filter coefficient.
