摘要 |
A compact spindle unit for a hard disk drive comprises a vertical shaft 1 fixed to a motor base 10 which also carries a stator coil 20. A cap-shaped hub 3 carrying a magnet 30 rotates about the shaft and is supported by a radial bearing R1 and a thrust bearing S1. The thrust bearing is constituted by a part 3b integral with the hub and either a flange 2 mounted on the shaft or an end surface of the shaft itself. At least one bearing surface 1d-1, 1d-2, 2a of each bearing is provided with dynamic pressure generating grooves. |
