摘要：
A voice-coil motor (VCM) with voice coils configured to reduce vibrations of a head when data is accessed on a disk in a disk drive. The VCM includes at least one VCM magnet and a voice-coil assembly. The voice-coil assembly includes a first voice coil and at least a second voice coil. The first voice coil is disposed in proximity to a magnetic pole of the at least one voice-coil-motor magnet. The second voice coil is disposed in close proximity to the first voice coil such that the first voice coil substantially overlays the second voice coil. The first voice coil and the second voice coil are configured to reduce vibrations of the head when data is accessed on a disk in the disk drive. A rotary actuator including the voice coils and a disk drive including the VCM are also provided.
