Spindle motor unit having hydrodynamic bearing |
摘要 |
In order to allow lubricant to move from the outside into the inside of a thrust bearing easily, an escape is provided in a base and a circumferential recess in a plate. As a result, a hub with magnetic disks mounted thereon can rapidly float up in a correct position at start-up of rotation thereby to perform correct recording and reproduction of information.
