A symmetric voice coil motor assembly having a central axis and including: a bearing assembly for rotation about the central axis; a coil assembly that is positioned radially outwardly from the bearing assembly and that has at least two pairs of coils and an inner yoke; a permanent magnet set that is positioned radially outwardly from the coil assembly and that includes at least two pairs of ring magnets and an outer yoke; and a head suspension assembly that is connected to the coil assembly and that includes a head gimbal assembly and an arm connected to the head gimbal assembly. The voice coil motor assembly may be a component in a hard disk drive, such as a micro drive.
