Hard disk drives of the invention are wrapped in wraps for enhanced sealing of the hard disk drive. Wrapped hard disk drives of the invention comprise: an enclosed hard disk drive housing comprising a base and a cover enclosed around internal components for facilitating reading and recording of data at a desired location on at least one disk contained within the housing; and a wrap wrapped and metallically sealed around the enclosed hard disk drive housing in an at least partially overlapping manner to form the wrapped hard disk drive and prevent undesired migration therethrough such that a sealed environment exists within the wrapped hard disk drive.

A system for boosting a concentration of a gas other than air, such as helium, within an enclosed disc drive environment includes a pressurized reservoir of the gas other than air within the disc drive environment. The gas other than air flows from the reservoir through an outlet and into the disc drive environment. Additionally, a particle trap within the disc drive environment traps air particles.

A docking adapter for reliably inserting and removing a memory storage-device from a memory storage device bay includes a rack and a removable carrier. The rack has a pair of lateral rails for holding the carrier, the carrier slidably engages the rails to enable the carrier to slide into the rack. The carrier is adapted for holding a hard disk drive. Teh carrier has a face with cooling fans, a cantilever mounted on the face for engaging the rack and a cover with a cam. The cover is hinged to the face. The cover rotates from a closed position where the cover parallels the face to an open position whee the cover opens, pressing the cam against the cantilever against the rack to smoothly extract the carrier from the rack.
摘要:
A system and method for decreasing power consumption of hard disk drives through use of an external atmosphere of low density gas, such as helium, is described. An environment container reasonably resistant to diffusion and leakage of helium (container) is erected around an existing hard disk array or server, wherein a helium mixture is pumped into the container. The helium mixture within the container is maintained at a specified concentration via proper tubing and valves which may be manually or automatically controlled. The actual concentration need not be very pure in order to achieve reduced drag over the disks in each of the hard disk drives, thereby achieving reduced power consumption. The environment container is stand alone from the hard disk drives used such that an altered hard disk apparatus is unnecessary.

A porous impregnation material (14) impregnated with a gaseous-phase lubricant that vaporizes at an atmosphere temperature within an outer case (2) is disposed in the inside of the outer case (2) that incorporates a tape mechanism (1) having a magnetic head such as a rotary video head (5). This allows the magnetic head to be in a state of being protected by a coating film of the gaseous-phase lubricant, thereby eliminating the adhesion of foreign substances other than the gaseous-phase lubricant to the magnetic head. As a result, decrease in the reading precision of magnetic data to be caused by the foreign substances can be prevented.

A lubricated disk drive (30) having a housing including a spindle motor, a clamp ring (78), a magnet (80), a wick structure (200), a disk (48), a wick housing (201), a wick cover (204), a wick spring (205) and a bearing housing (66) supports an inner hub (68), an outer hub (70), a shaft (72), a thrust bearing (67) and a stator assembly (74) including a stator lamination and windings.
摘要:
The invention relates to a CD-player which includes a turntable (56) intended for contact with a CD-disk (6) and having a motor-driven shaft. The arrangement includes an optical unit (10) which functions to project a laser beam onto the surface of the CD-disk as the unit scans the disk from its periphery to its centre, the unit detecting laser light that is reflected back to the unit after having been modulated with information stored on the disk. The turntable (56) and the motor-driven shaft (58) are supported for rotation through the agency of an air journal or bearing unit (12), to facilitate the work of the drive motor (8) and to reduce mechanical disturbances.
