ABSTRACT:
In an assembly method for a disk recording apparatus, a spindle motor is driven to rotate disks and with the disk recording apparatus supported by a linear guide mechanism for movement with one degree of freedom of translation in a direction substantially in parallel to surfaces of the disks. A measuring mechanism is used to measure vibration in the direction of the one degree of freedom of translation caused by the rotation of a rotating part of the disk recording apparatus. An angular position detecting mechanism is used to detect the angular position of each disk at which vibration of a maximum amplitude is generated. The eccentricity and the direction of eccentricity of the rotating part are analyzed in accordance with the measured vibration and the detected angular position, and the base and the rotating part are moved relatively to correct the eccentricity in accordance with the result of the analysis.
