Data head load beam for height compacted, low power fixed head and disk assembly

A high capacity miniature fixed disk drive within a standardized micro-Winchester form factor comprising:

• housing means defining a floor and contiguous integral sidewalls,
• cover means for enclosing the housing means and thereby defining a sealed internal ambient space,
• disk spindle means extending from the floor within the space, the disk spindle means including an in-hub direct drive brushless DC spindle motor means,
• at least six data storage disks mounted in stacked, spaced apart arrangement on the disk spindle means and rotated by the spindle motor means, the disks having a diameter not substantially greater than 95 millimeters, there being a space between oppositely facing data storage surfaces of adjacent disks having a height dimension not substantially greater than about one tenth of an inch, the data storage disks defining at least twelve data storage surfaces, the surfaces defining at least 50 megabytes of user data in a multiplicity of concentric data tracks and prerecorded with embedded sector head position servo information providing sector identification and track centering information;
• mass balanced rotary voice coil actuator means mounted to the floor within the space and including at least seven aligned vertical head arms;
• at least twelve elongated load beams, each load beam being attached to a said head arm to be in substantial in-line alignment therewith along a longitudinal axis, each load beam being formed so as to define:
• a reinforced attachment end region for attachment to a said vertical head arm;
• a leaf spring loading region adjacent to the attachment end region;
• a gimbal flexure attachment region adjacent to a head end region,
• a longitudinally reinforced loading tab region extending outwardly from the head end region for cooperating with a loading ramp means at least during disk drive assembly for loading a data transducer head slider into proximity with an adjacent data surface of a said disk, and
• a reinforced load beam region between the leaf spring region and the head end region and comprising longitudinal reverse flange peripheral edge portions for stiffening said load beam region in a direction along the longitudinal axis;
• gimbal flexure means attached to the load beam means at the gimbal flexure attachment region;
• the data transducer head slider being attached to the gimbal flexure means and including plural electrical connections to a data transducer head defined thereon;
• head conductor wire means connected to the plural electrical connections and dressed along one of said reverse flange peripheral edge portions;
• and,
• drive electronics means being connected to said spindle motor means, said actuator means and each said data transducer head,
• the housing defining a loading ramp region for placement of said loading ramp means in cooperation with said loading tab regions to facilitate loading said head sliders relative to respective adjacent data storage surfaces, at least during initial assembly of said disk drive.
