| description | An actuator for positioning transducers with respect to a disk storage device data surface provides a substantially sealed head-disk enclosure from which the voice coil motor permanent magnets are excluded. The mounting flange (61)-inner core (12) member, end cap and collar (60) and shorted turn (57) provide a sealed enclosure about the transducer carriage (30), voice coil (37) and working air gap of the voice coil motor (VCM) with the permanent magnet and outer core pieces (65) assembled to the device thereafter. The permanent magnets can be excluded from the clean room assembly area and this source of the most destructive particulate contamination are outside the head-disk enclosure. |
