IPC: G11B19/20
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To grasp a magnetic fluid in utilizing a leakage magnetic flux of a disk chucking magnet and to confine the magnetic fluid in its position. SOLUTION: A shaft 16 is inserted into a cylindrical body 30, and a viscous fluid 32 is sealed between this shaft and the cylindrical body to form a fluid bearing part 40. A fluid sealing 50 is provided on an upper end side of the fluid bearing part. This means is composed of recessed annular parts 54 and 55 and a magnetic fluid 61 sealed in a gap between them. Magnetic flux passing through a cylinder body 21 by the recessed annular parts becomes easily leakable in these parts, and the leakage magnetic flux is grasped to be confined in the recessed annular parts. A passage for passing the recessed annular parts is interrupted by the confinement of the fluid in virtue of this magnetic flux, so that the fluid 32 and the magnetic fluid itself are never leaked to the outside.  Since a magnet to be exclusively used for attracting the magnetic fluid is not required, the structure can be miniaturized and thin structive by a space for this magnet.
