A system and method for uniform cooling of an electromagnetic coil are provided. The system includes an electromagnetic coil, a cooling structure, and a cooling fluid source. The cooling structure surrounds the entirety of the perimeter of the electromagnetic coil, and includes a first cooling channel and a second cooling channel arranged alternately about the electromagnetic coil. The cooling fluid source is configured to deliver a first cooling fluid to the first cooling channel and a second cooling fluid to the second cooling channel, such that the first cooling fluid and the second cooling fluid cool the electromagnetic coil.

Aerodynamic forces contribute to disk and actuator vibration leading to track positioning errors in storage devices such as hard disk drives. The invention provides a variety of dampening mechanisms and a method of dampening to alleviate these problems in single disk storage devices. This includes disk drives of at most 13 millimeters in height.

An optical variable attenuator having a reflector in a first position, and a mechanical device for positioning the reflector from the first position to a second position is disclosed. The optical variable mechanical device comprises a first and second guide slots, a moving part, and a screw, where a first guide slot is placed parallel to the second guide slot. The moving part is placed in between and extending in the parallel direction to the first and second guide slots, the screw extending into and away from the moving part. Optionally, a lock pin is used to mount a moving part to avoid injecting any tip and tilt errors. The lock pin is guided by two machined slots on a main body of a variable optical attenuator. Alternatively, two springs loaded balls are positioned in tight contact of the guide slots on the move part, instead of a lock pin.
