  • Patent number: 6493187
    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.
    Type: Grant
