A disk drive includes a base, a disk rotatably coupled to the base, and a
rotary actuator coupled to the base adjacent the disk. The rotary
actuator is configured to pivot about an axis of rotation, and includes a
coil. The disk drive further includes a magnetic element support coupled
to the base. The magnetic element support includes first and second plate
sections cooperatively formed to receive the coil. The magnetic element
support includes a first transition section formed between the plate
sections for forming a first magnetic flux path. The first transition
section disposed angularly lateral with respect to the coil and the axis
of rotation. The magnetic element support includes a second transition
section formed between the plate sections for forming a second magnetic
flux path. The second transition section being disposed radially beyond
the coil with respect to the axis of rotation.
