摘要： 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.

摘要： A novel head stack assembly (HSA) includes a flex cable with a first side and an opposing second side, and having a hole therethrough. The HSA also includes a head gimbal assembly (HGA) having a load beam, a laminated flexure attached to the load beam, and a head attached to the laminated flexure. The laminated flexure includes a flexure tail with a snap-through feature. The snap-through feature has a plurality of windows in the flexure tail, a snap-through feature central portion that is centric to the plurality of windows, and a plurality of lobes. Each lobe extends out from the snap-through feature central portion radially into one of the plurality of windows. The laminated flexure overlies and contacts the flex cable on its first side, but the snap-through feature is disposed through the hole so that each of the plurality of lobes contacts the flex cable on its second side.

摘要： The present invention relates, in one aspect, to an apparatus for positioning a disk drive head over a disk which is a part of a disk drive assembly. A disk drive apparatus includes a base plate, a disk coupled to the base plate, a disk drive head assembly arranged over the disk, and an actuator assembly that is arranged to position the disk drive head assembly over the disk. The actuator assembly is coupled to the disk drive head assembly, and includes a ferrite piece and a crash stop contact point that is separate from the ferrite piece. The disk drive apparatus also includes a magnetic latching assembly which has a plate extension that is substantially stationary with respect to the disk, a magnet nest that is movably mounted over the plate extension, and a latch magnet that is coupled to the magnet nest. A crash stop, which is also included in the disk drive apparatus, is arranged to be contacted by the crash stop contact point when the disk drive head assembly is positioned in a parking position.

摘要： A flexible circuit assembly to provide communication to and from data transducer heads located on a load beam of a suspension assembly of a disk drive. Two discrete preamplifier integrated circuits, one of which has a pin-out that is a mirror image of the other, are mounted on a flexible circuit substrate such that the mirror image preamplifier integrated circuit mounted thereon folds underneath the first preamplifier integrated circuit. A head-arm access strip of the flexible circuit is installed in a distorted S-shaped bow in order to reduce the force on the suspension assembly.
