ROTARY EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide rotary equipment in which much more recording disks can be loaded while the balance performance of a rotary body during the rotation of the rotary body is satisfactory.SOLUTION: Rotary equipment 100 is configured such that a fixed body side shaft 26 is enclosed via lubricant 92 by a rotary body side sleeve 106. A first clearance 126 between the shaft 26 and the sleeve 106 includes two radial dynamic pressure generation sections 160 and 162 isolated from each other along an axial direction. The rotary body and the fixed body are configured such that a center of gravity G of the rotary body when a plurality of magnetic recording disks 8 are placed on the rotary body is positioned between the two radial dynamic pressure generation sections 160 and 162.
