Title: Metal thin film type magnetic recording medium and manufacturing method therefor
Inventor: KANEKAWA ICHIRO
IPC: G11B5/735
Filed: 2001-06-07
Abstract: PROBLEM TO BE SOLVED: To attain downsizing of a metal thin film type magnetic recording medium without reducing the conventional mechanical strength thereof and to prevent the generation of thermal distortion. SOLUTION: A reinforcing layer 2 is deposited on the surface opposite to a magnetic layer 4 of a non-magnetic substrate 1 of the metal thin film type magnetic recording medium 100. Since the non-magnetic substrate having relatively low rigidity is interposed between the magnetic layer and the reinforcing layer both having relatively high rigidity, the distribution of rigidity is made uniform and whole mechanical strength is further enhanced. Since the non- magnetic substrate adheres closely to a cooling member by the electric charge the reinforcing layer has and the heat generated when the vacuum thin film is deposited is satisfactorily transmitted to the cooling member and dissipated, generation of the thermal distortion of the non-magnetic substrate can be prevented.

Title: Measurement device
Inventor: ITO KOJI
IPC: G01B5/02
Filed: 2001-06-15
Abstract: PROBLEM TO BE SOLVED: To improve reliability of a measurement device 1. SOLUTION: A control device 4 compensated for the error of a measurement jig 2, using a master 10 (resets so that the display number value agrees with the standardized dimension of the master 10) and thereafter determines whether the compensated display number value is normal or anomalous. Specifically, after resetting, the control device 4 compares the movement quantity of a jig spindle 6 to the normal movement quantity, and then determines 'abnormality' to warm to a worker the abnormality, when the difference between both the movement quantities exceeds an allowable value. That is, the error caused from a foreign material is compensated, in addition to the error caused from the influence of the wear of the measurement jig 2 or the change in the room temperature, when the foreign material is stuck to the measurement jig 2 or the master 10.  In this case, the movement quantity of the jig spindle 6 of necessity increases as compared to the case when the measurement jig 2 and the master 10 are clean, and therefore the control device 4 can determines 'abnormality', when the movement quantity of the jig spindle 6 exceeds the allowable value.
