Disk drive including a pair of actuator coils each with a radial segment generally perpendicular to inner and outer segments and overlapping with inner and outer magnets

摘要

A disk drive includes a magnetic element having an inner magnet and an outer magnet. The disk drive further includes a first coil. The first coil includes a first coil inner segment, a first coil outer segment, and a first coil radial segment disposed generally perpendicular to the first coil inner segment and the first coil outer segment. The first coil radial segment overlaps the inner and outer magnets within a magnet periphery throughout a fill range of motion of the actuator. The disk drive further includes a second coil. The second coil includes a second coil inner segment, a second coil outer segment, and a second coil radial segment disposed generally parallel to the first coil radial segment. The second coil radial segment overlaps the inner and outer magnets within the magnet periphery throughout the full range of motion of the actuator.
