<p>PROBLEM TO BE SOLVED: To provide a disk driving device that prevents attachment of a lubricant emitted from a fluid dynamic pressure bearing to a disk surface and can reduce occurrence of malfunction.SOLUTION: A disk driving device comprises: a rotor that allows mounting of a disk to be housed in a disk housing space to be formed between a chassis and a top cover to be fixed to the chassis, and rotates; and a fluid bearing unit that supports the rotor in a manner rotatable to the chassis. In the fluid bearing unit, a prescribed area is filled with a lubricant and a capture body for capturing the lubricant to be emitted from a gas-liquid interface is provided in a space extending from the gas-liquid interface of the lubricant to the disk housing space.</p> |
