摘要： A host operating system (OS) can function as a task under a disk drive operating system. The host OS and the disk drive operating system can be run on a single processor. The processor is able to maintain the real-time response characteristics of a disk drive controller. A shared memory subsystem can be accessed by both operating systems. A disk drive storage device can access and respond to metadata about an underlying file system maintained by a host operating system (OS) to optimize data transfers between the disk drive and the host OS. The disk drive can identify the nature of read/write accesses, allowing it to prioritize and performance optimize the accesses. The disk drive can perform these functions without any changes to the block interface.

摘要： An improved magnetic head for a hard disk drive including a lead overlaid read head in which the read width and read gap are reduced. The read width, which corresponds to the distance between the inner ends of the overlaid electrical leads, is reduced by the fabrication of a thin read width insulation member prior to the fabrication of the overlaid electrical leads. The read gap is reduced by fabricating the overlaid electrical leads from a magnetic, electrically conductive material such as NiFe, whereby the overlaid electrical leads also function as a magnetic shield. The read gap, which is the distance between the first and second magnetic shields is thus reduced as compared to the prior art by the thickness of the electrical leads and the thickness of the prior art second insulation layer formed between the electrical leads and the second magnetic shield.

摘要： A micro-fabricated chip having a stationary structure and a movable structure with a gimbal structure allows pitch and roll motion of the movable structure with respect to the stationary structure. One embodiment of the gimbal structure includes a dimple surface making a rolling-type contact with the stationary structure, and a center bar and a plurality of bar members. An alternative embodiment of the gimbal structure includes a plurality of torsion bar members. Another alternative embodiment of the gimbal structure includes a plurality of flexible members. The micro-fabricated chip can be a passive chip structure or, alternatively, a microactuator having a movable structure that moves in a rotational direction or a translational direction with respect to the stationary structure.

摘要： The present invention provides a magnetic disk unit capable of attaining miniaturization, lower cost, lighter weight, lower profile, and higher density. [Solution] To that end, only a carriage 20, and a spindle motor 30 among respective constituent components of HDD 1 are securely attached to a support plate 70 made of a hard metal material higher in rigidity than a shroud 80. All the constituent components of HDD 1, except the carriage 20, and the spindle motor 30, (a voice coil motor 40, a ramp 50, a latch lever 60, an HDD connector 92 and so forth), that is, the respective constituent components of HDD 1, of which assembling precision, rigidity, and so forth are not required, are attached to the shroud 80 small in wall thickness, and lighter in weight, formed of a resin material such as plastics and so forth.

摘要： Solder used for solder bonding which is powerful as a technique that seals the space between the feedthrough and the base of a magnetic disk device is low in proof stress as material, so that it is difficult to ensure sufficient bonding reliability for external force applied to a magnetic disk device during manufacture and in a users' environment. An opening 7 of a through hole is provided on the bottom of the base 2 of the magnetic disk device 20 and a feedthrough mounting plane 8 which is one of the steps formed toward the outside of the device is provided around the opening 7. The feedthrough 1 includes a flange 4 and pins 3 which are fixed to the flange 4 by a glass material 5 and pass an electric signal. The flange 4 is larger in outer shape than the opening 7 of the base 2. The periphery of the flange 4 of the feedthrough 1 is mounted on the feedthrough mounting plane 8 of the base 2 from the outside and bonded thereto by solder.

摘要： A method for producing high resolution nano-imprinting masters is disclosed. The method inverts the negative features of an exposed and developed positive e-beam resist to positive features in the patterned silicon nitride layer of the nano-imprinting master. A first, oxidation resistant, mask layer is used to pattern a DLC layer deposited on the silicon nitride layer. After patterning the DLC layer, the negative features of the DLC layer are filled with deposited metal, which creates a second mask layer subsequent to the removal of the remaining DLC layer. The second mask layer is used to etch the silicon nitride layer, creating the final nano-impmting master.
