摘要： A data storage device involves a plurality of continuous sidewalls and corner portions of a tub cover overlapping with and hermetically sealed with a corresponding plurality of sidewalls and corners of an enclosure base using an epoxy adhesive. Base protrusions and/or cover dimples may be used to set a suitable gap between the parts. A robust hermetic seal provides for filling the HDD with a lighter-than-air gas. A tub cover may include corners having a tapered radius that decreases from the top to the bottom edge, and a base may include corners having a constant-radius outer surface and sidewalls having a sloped upper surface, whereby an assembly interference fit between the base and the tub cover is formed by forcing outward each sidewall of the tub cover while forcing inward at least a portion of each corner of the tub cover.

摘要： An example storage device may include a sealed enclosure that encloses an atmosphere comprising a gas. The sealed enclosure may enclose a storage medium and a read-write head including a thermal flying-height control (TFC) heater and an embedded contact sensor (ECS) including a DC resistance (DCR) sensor. A DC resistance exhibited by the DCR sensor may be indicative of a temperature sensed adjacent the DCR sensor. The storage device may include a controller. The controller may cause a current to be applied to the TFC heater to generate heat, receive a signal from the ECS indicative of the temperature sensed by the DCR sensor, and determine a composition of the atmosphere or a concentration of the gas based on the signal.

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.

摘要： A novel hermetically sealed disk drive comprises a disk drive enclosure that includes a disk drive base with a bottom face, four side faces, and a top cover. The disk drive also comprises a peripheral foil seal overlapping each of the four side faces and having a first opening therethrough that overlies the upper surface of the top cover. The peripheral foil seal conforms to the disk drive enclosure and is adhered to the top face and to each of the four side faces by a first continuous adhesive layer. The hermetically sealed disk drive also includes a central metal cap completely covering the first opening and being adhered to the upper surface of the top cover through the first opening by a second continuous adhesive layer. The central metal cap is thicker than the continuous metal foil, and the disk drive enclosure is helium-filled.

摘要： An altitude sensor includes a support frame and a sensor unit mounted in the support frame. The support frame has an upper shield and a lower shield. The sensor unit includes a beam and a damper. The damper is configured to move up and down in response to the air flow, which drives the beam to move up and down accordingly. Distances from the damper to the upper shield and the lower shield are less than those from the beam to upper shield and the lower shield. The altitude sensor possesses super specific properties such as unlimited sensitivity to flying height because of no size constraints and unchanged sensitivity under a changing environment, a selfprotective mechanism to resist deformation in case of an accident, easy manufacture process as well as low production cost. The present invention also discloses an altitude sensor for use in a disk drive device and a disk drive device with the altitude sensor.

摘要： Embodiments of the present invention help to prevent leakage of low-density gas during low-density gas injection into a disk drive device and to perform low-density gas injection efficiently. In a hard disk drive (HDD) according to one embodiment of the present invention, an injection hole filter with a valve function is attached to a helium injection hole in order to inject helium gas in an enclosure. The injection hole filter has a valve member configured to operate in an open state or closed state. The open state is a state while the helium gas is being injected and the closed state is a state after the helium gas has been finished to be injected. The valve member is in the open state if the outside pressure is higher than the inside pressure and is in the closed state if the inside pressure is higher than the outside pressure.
