摘要: An apparatus for vibration reduction in a hard disk drive, the hard disk drive comprising at least one hard disk and at least one actuator arm. The apparatus comprises a flow mitigating device disposed on the at least one actuator arm, the flow mitigating device comprising at least one surface being inclined with respect to a reference plane of the actuator arm to generate streamwise vortices for interacting with and weakening vortex structures generated at a trailing edge of the actuator arm during spinning of the hard disk.

摘要: According to an embodiment of the present invention, a data storage device comprising a motor having a stator is disclosed. The stator may include a substrate having a first surface and a second surface opposite to the first surface; and a n-phase winding arrangement having n phase windings; wherein each phase winding comprises m flat fractional-pitch coils arranged on the first surface of the substrate such that the coils are spaced apart uniformly along a closed loop and connected in series; wherein each coil together with an angular section of the substrate between the coil and an adjacent coil of the same phase winding defines a stator pole-pair; and wherein m is an integer larger than 1.
