摘要： Certain example embodiments relate to torsion compensation coils that cooperate with primary coils in voice coil motors of disk drive devices, and methods of making the same. In certain example embodiments, a voice coil motor is provided which may include a single external magnet. A primary coil may be located above the external magnet, with the primary coil being capable of receiving a first current. At least one torsion compensation coil may be connected to the primary coil. The at least one torsion compensation coil may be capable of receiving a second current. The at least one torsion compensation coil may be configured to reduce torsion and/or bending forces introduced by the first current passing through primary coil and/or magnetic field leakage from the external magnet.

摘要： A base for a data storage system is provided having an inner facing surface and an outer facing surface. The base includes a motor well. Formed with inner surface of facing surface of the base includes a medium region, an actuator region and a dam. The medium region is defined by a medium region planar surface surrounding a portion of the motor well, a leading surface and a trailing surface. The actuator region is defined by an actuator region planar surface that is recessed from the medium region planar surface, the leading surface, the trailing surface and a remaining portion of the motor well. The dam has a dam planar surface that surrounds the remaining portion of the motor well and is positioned on the actuator region planar surface between the leading surface and the trailing surface.

摘要： A vibration testing apparatus comprises a first mooring bar coupled to the base; a second mooring bar coupled to the base such that the second mooring bar is disposed away from and faces the first mooring bar to define a space between the first and second mooring bars; a first strap comprising a first end secured to the first mooring bar, and a second strap comprising a first end secured to the first mooring bar. A second end of each of the first and second straps may be secured to the second mooring bar such that the first and second straps span the space between the first and second mooring bars and such that a tension on at least one of the first and second strap is controllable.
