Title: Method and instrument for measuring groove shape
Inventor: OTOTAKE MASABUMI
IPC: G11B7/26
Filed: 1989-04-28
Abstract: PURPOSE:To detect the groove shapes of an optical disk with high accuracy and to automate the decision of the acceptance or rejection thereof by determining the cross sectional shape of the groove width and groove depth by the diffraction intensities of zero order, 1st order and 2nd order diffracted light rays of the collimated beams of the coherent light projected to the grooves and the intervals of the grooves. CONSTITUTION:The laser beam projected the optical disk 1 is diffracted on the surface by the track grooves thereof. The diffracted light thereof is detected by a photodetector 3 and the intensity thereof is photoelectrically converted and is measured by an optical power meter 33. The photodetector 3 consists of three optical sensors; the zero order optical sensor 3a which detects the zero order diffracted light, the 1st order optical sensor 3b which detects the 1st order diffracted light diffracted at the 1st order diffraction angle theta1 with the zero order diffracted light and the 2nd order optical sensor 3c which detects the 2nd order diffracted light with the inclination at the 2nd order diffraction angle theta2 with the zero order diffracted light. The intensities of the respective optical sensors 3a to 3c of the photodetector 3 measured by an optical power meter 33 is applied to a host computer 5 where the depth and depth of the cross section of the track grooves are calculated. The measurement accuracy is improved in this way and the groove shapes of the plural places are measured by relatively moving the optical means and optical disk. The acceptance or rejection thereof is thus automatically decided.

Abstract: PURPOSE: To obtain stable and durable cushion effect by mounting the cylindrical cushion sleeve, with the elastic material, on the cushion rod core which is tapered by stages at the top of the piston rod.  
     CONSTITUTION: The cushion sleeve 14 is elastically fitted by the spring washer 16 around the cushion rod core 7 which is tapered by stages at the top of the piston rod 3.
