摘要： A hermetically-sealed hard disk drive (HDD) involves the inner surfaces of sidewalls of a second cover overlapping with and adhesively bonded with the outermost surfaces of sidewalls of an enclosure base. Matching angled sidewalls for the inner and outermost surfaces, and an adhesive bond that provides a hermetic seal in which a ratio of the height to the thickness of the adhesive bond is in a range of 50-100:1, may be utilized to provide a hermetic seal having a long, narrow diffusion path to inhibit diffusion of gas through the adhesive bond. The second cover may include preformed corner corrugations, and the base may include corner pockets in which corner pleats, formed with the corner corrugations by bending inward the cover sidewalls, are received within when the cover and base are bonded together.

摘要： A low permeability electrical feed-through involves a laminated structure having a conductor layer sandwiched between adjacent insulator layers, which are sandwiched between adjacent diffusion control layers, where the laminated structure provides a relatively narrow and long, high aspect ratio diffusion channel to inhibit the leakage of gas from within a sealed device to the external environment. The electrical feed-through may comprise lower and upper electrical connection pads that are positioned within different regions of the feed-through but still electrically connected by way of a first via positioned in a sealed region, the conductor layer, and a second via positioned in an external environment region.

摘要： A magnetic recording system configured for recording to a bit patterned media using both hypertrack recording and shingled recording. The magnetic recording system includes a write pole with a notched trailing edge that results in a write bubble with a trailing edge that has two outer convex lobes separated by a centrally disposed concave region. By locating one of the lobes over first and second data tracks of a hypertrack, a proper alignment of the relative phase of the two tracks can be maintained. Further adjustment to the alignment can be achieved by adjusting the radial location of the write head.

摘要： A method for manufacturing a bit patterned magnetic media for magnetic data recording. The method includes selectively depositing a self assembled monolayer over a seed layer and then oxidizing the deposited self assembled monolayer. The self-assembled monolayer can be deposited by use of a stamp to form a pattern covering areas where a non-magnetic segregant (such as an oxide) is to be formed and openings where a magnetic material is to be formed. A magnetic alloy and a segregant (such as an oxide) are then co-sputtered. The magnetic alloy grows only or selectively over the seed layer, whereas the segregant grows only or selectively over the oxidized self-assembled monolayer.

In a first example, a data storage assembly includes an enclosure configured to house at least one data storage device and a fan assembly configured to provide airflow within the enclosure to ventilate the at least one data storage device. A plurality of acoustic waves emanate into the data storage device from one or more fans of the fan assembly during operation. An acoustic attenuation device is positioned within the enclosure and configured to deflect at least a first portion of the plurality of acoustic waves away from the at least one data storage device and absorb a portion of acoustic wave energy of at least a second portion of the plurality of acoustic waves.

摘要： A method of assembling a data storage device comprises forming an enclosure by overlapping each of a plurality of sidewalls of a cover with a corresponding sidewall of a base part, dispensing a liquid adhesive between the respective sidewalls of the cover and base part in such a quantity at each of a plurality of locations to promote capillary flow of the liquid adhesive to form a continuous film of liquid adhesive between the sidewalls, and curing the continuous film of liquid adhesive to form a hermetic seal between the cover and the base part. Embodiments may include surface treating the sidewall surface(s), which can help promote the capillary flow of the liquid adhesive. The hermetic seal provides for a lighter-than-air gas to be held therein.
