Abstract: A disk drive includes a storage disk, a data transducer, an actuator assembly and a positioner. The actuator assembly supports the data transducer over the storage disk. The actuator assembly includes a rotatable actuator hub and a longitudinal axis. The positioner moves the actuator assembly to position the data transducer relative to the storage disk. During movement of the actuator assembly, the actuator hub is subject to a resultant force that causes track misregistration of the data transducer. The positioner includes a magnet assembly that generates a magnetic field, a first conductor region and a second conductor region. In one embodiment, the conductor regions cooperate with the magnet assembly to generate a first force and a second force that are each directed at an angle having an absolute value that is greater than zero degrees and less than approximately 45 degrees relative to the longitudinal axis of the actuator assembly.

Abstract: A height reduced rotary voice coil actuator assembly includes an E-block defining one or more vertically aligned short tines. Fastened to each short tine are one or two elongated tine extenders. The tine extender-short tine connection occurs outside the region above and below the data storage disks. A peg-leg load beam having tabs adapted to receive wires having no protective plastic tubing is connected to each tine extender. The wires are bonded directly to the tabs and provide electrical communication between data transducer heads located on the load beam and drive electronics. A swage boss formed in the tine extender faces outwardly in the same direction as a data transducer head assembly supported by the peg-leg load beam. Each short tine is substantially coplanar with an associated data storage disk and lies beyond the outer periphery thereof. The resulting in-line rotary actuator achieves substantial vertical or Z height compaction.
