Abstract: The present disclosure generally relates to data storage devices, and more specifically, to a magnetic media drive employing a magnetic recording head. The head includes a trailing shield, a main pole, an STO disposed between the trailing shield and the main pole, and a non-magnetic conductive structure adjacent to the main pole and in contact with the STO. The STO includes an FGL and an SPL, and the FGL is disposed between the main pole and the SPL. The FGL includes a side extending over the main pole and at least a portion of the non-magnetic conductive structure. With the FGL disposed proximate to the main pole and over at least a portion of the non-magnetic conductive structure, current crowding and disturbance from the trailing shield are minimized.

The filter unit includes a base section fixed to an inner surface of the casing, a holding frame coupled to the base, and a collection filter detachably held in place by the holding frame.

Abstract: A valve apparatus for a storage device includes a tab configured to couple to an enclosure and a flap coupled to the tab by a flexure. The flap is configured to regulate airflow through a breather hole of the enclosure. The flap includes an opening configured to reduce airflow into the enclosure when the flap is in a closed position.

Abstract: A solid state drive apparatus includes a housing having a first accommodation space and a second accommodation space; a substrate mounted in the first accommodation space, wherein at least one non-volatile memory chip is mounted on the substrate; and a heat dissipation member mounted in the second accommodation space and including an isolation barrier that defines a boundary between the second accommodation space and the first accommodation space and a plurality of fin portions that extend from the isolation barrier away from the first accommodation space, wherein a plurality of through air holes are provided in a side of the housing adjacent the second accommodation space.

Abstract: A system for storing long-term digital data comprises data storage equipment including one or more data storage devices 26 stored in a sealed data storage module 10, which is positioned within a data center enclosure 101, which contains a body 12 that is surrounded by a strengthening shield 14. The body contains a network of tunnels 16. One or more data storage modules 10 are stored in a tunnel 16 that is inaccessible to human beings and comprises robotic movement means. Data can be stored before or after the data storage device 26 is sealed within the data storage module body. A utility distribution system can be positioned in proximity to the data storage module 10 for the utility distribution module to provide contactless power and network connection to the data storage module and for the data storage module to retrieve and transmit to the utility distribution module 34 data that is held in the data storage device 26.

Abstract: An iron-oxidized hard disk drive (HDD) cover has an inner surface that is substantially free of un-oxidized or pure metallic iron, fabricated by baking a stainless steel cover and thereby oxidizing the cover surface of iron. Because the cover is iron-oxidized, a costly nickel-plating process may be foregone while a “Fe smear” problem may be significantly reduced. Such an iron-oxidized cover is especially beneficial for, though not limited to, use as an inner cover in a sealed HDD.

Abstract: According to one embodiment, a disk device includes a disk recording medium, a drive motor configured to support and rotate a recording medium, a suspension assembly which supports a head, a housing containing the recording medium, the drive motor and the suspension assembly, a filter in the housing, opposite to part of an outer peripheral edge of the recording medium, and through which an airflow generated by rotation of the recording medium flows, an exhaust hole formed at the housing and located opposite to an upstream side of the filter with respect to the airflow, and an air-intake formed at the housing and located opposite to a region of the housing, whose pressure is lower than the pressure of the upstream side of the filter.

Abstract: A disk drive includes an enclosure that has a breather port therethrough. A first labyrinth path may be disposed inside the disk drive enclosure, in fluid connection with the breather port. A second labyrinth path may be temporarily disposed outside the disk drive enclosure, in fluid connection with the breather port. An alternative gas such as helium may be allowed to bleed out through the second labyrinth path during a period of servo track writing. The second labyrinth path may be removed after servo track writing.

Abstract: In a disk drive device having a double cover structure with low-density gas enclosed therein, embodiments of the present invention help to securely perform leak inspection on an outer cover and to prevent defects caused in joining the outer cover. According to one embodiment, a hard disk drive (HDD) comprises a flow amount adjuster on a base-facing side of its inner cover. Helium gas in an enclosure goes out through a ventilation hole via diffusion channel of a flow amount adjuster. The emitted helium gas remains in the space between the inner cover and an outer cover. This achieves easier detection of the leakage of helium gas from the joining section of the outer cover and prevention of emission of too much helium gas from the enclosure.

Abstract: There is provided a base plate for a hard disk drive including: a disk accommodating part on which a disk having data stored therein is disposed; a head seating part formed to be lower than a position of the disk accommodating part and including a head driver disposed thereon providing driving force to a read-write head reading the data stored on the disk; a filter seated on the disk accommodating part and collecting foreign objects from air flowing during rotation of the disk; and a filter fixing part formed by punching a portion of the disk accommodating part and vertically raising the portion of the disk accommodating part, and fixing the filter.

Abstract: Embodiments in accordance with the present invention provide a magnetic disk drive that reliably prevents entry of water or other form of liquid through a breathing hole for the enhanced performance, reliability, and the like. In one embodiment, a box body forming part of a hard disk drive (HDD) has a top cover. The top cover includes a breathing hole drilled therein. The breathing hole serves to eliminate any pressure difference between an inside and an outside of the HDD. A fiber waterproof body, which includes a waterproof fiber material or the like, is fitted in a large-diameter hole of the breathing hole. A pore waterproof body, formed by bundling up a large number of slender pores, is mounted in a small-diameter hole of the breathing hole.
