摘要： According to one embodiment, a disk storage apparatus includes a write controller and a refresh controller. The write controller is configured to perform shingled write, writing data on a disk, using, as write units, data areas including groups of tracks. The refresh controller is configured to count the number of times the shingled write has been performed in a data area adjacent to the inner or outer circumference of a data area, in accordance with a weighting value set on the basis of a shingled write direction, and to instructs that a refresh process be performed, when the number of times counted exceeds a threshold value.

摘要： In one embodiment, a seed layer, an underlayer, and a magnetic domain control layer are laminated on both sides of a magnetoresistive sheet unit. A lower electrode film is thinly formed on an upper portion of the magnetic domain control film. A portion of the lower electrode film near the magnetoresistive sheet unit does not protrude substantially from an upper surface of the magnetoresistive sheet unit. Should the portion protrude, a step from the upper surface of the magnetoresistive sheet unit is about 14 nm or less. This portion and the upper surface of the magnetoresistive sheet unit are formed into a flat surface. An upper electrode film is formed thickly on an upper portion of the lower electrode film on an outside thereof so as to circumvent the flat surface. A protective layer, an upper gap film, and an upper magnetic shield film are also formed.

摘要： Embodiments of the invention provide a reading head structure that ensures a stable magnetic moment of a pinned layer against a great external magnetic field, and minimizes the pinned-layer damage occurring during air-bearing surface machining. In one embodiment, a magnetoresistive head is based on a spin-valve effect and has free layers, a stacked-type pinned layer, and an electroconductive nonmagnetic spacer layer positioned between the free layers and the stacked-type pinned layer. The stacked-type pinned layer includes three ferromagnetic films, and antiferromagnetic coupling films interposed between the ferromagnetic films. Of these ferromagnetic films, the first two films have a high coercivity and a high resistivity. The third ferromagnetic film is made of a material that gives a great magnetoresistive effect. The sum of the magnetic moments generated from the stacked-type pinned layer is substantially zero.

摘要： Embodiments of the present invention help to reduce etching damage at end parts of a magnetoresistive sensor in ion beam etching. According to one embodiment, ion beam etching (IBE) is used in a magnetoresistive sensor track width forming step. This IBE irradiates Ar ion beam to a substrate in a state that the substrate is inclined and further rotates the substrate about its normal as a rotational axis. In a conventional track width forming step, the IBE irradiates the Ar ion beam to the substrate all the time while the IBE is rotating the substrate. By contrast, the IBE according to embodiments of the present invention irradiates the Ar ion beam to the substrate only in a predetermined specific angular range.

摘要： Embodiments of the invention provide a reading head structure that ensures a stable magnetic moment of a pinned layer, even in a very small sensor, against a great external magnetic field, and minimizes the pinned-layer damage occurring during air-bearing surface machining, and provide a reading head not suffering the deterioration of a pinned layer in terms of magnetic structure when the head is actually used in a hard disk. In one embodiment, a magnetoresistive head is based on a spin-valve effect and has free layers, a stacked-type pinned layer, and an electroconductive nonmagnetic spacer layer positioned between the free layers and the stacked-type pinned layer. The stacked-type pinned layer includes three ferromagnetic films, and antiferromagnetic coupling films interposed between the ferromagnetic films. Of these ferromagnetic films, the first two films have a high coercivity and a high resistivity. The third ferromagnetic film is made of a material that gives a great magnetoresistive effect. The sum of the magnetic moments generated from the stacked-type pinned layer is substantially zero.

摘要： A magnetic recording has very low warp characteristics but excellent film characteristics. Particularly, the recording medium has a high coercivity with a small range of coercivity distribution, with a warp characteristic below 3 .mu.m per radial inch. The medium is formed by heating a substrate at a high temperature with a temperature distribution on the substrate that is improved by the use of a heat distribution mask, which reduces the temperature distribution of the substrate to below .+-.3%.

摘要： A weft picking system for an air jet loom provided with a microcomputer as a controller. The weft picking system comprises a weft traction device including a pair of rollers one of which is driven by an inverter motor. A weft yarn fed from a weft measuring and storing device can be put between the rollers to be drawn toward a weft posture regulating nozzle. The weft posture regulating nozzle is arranged to project the weft yarn into the shed of warp yarns while regulating the posture of the weft yarn, under the influence of an air jet ejected therefrom and under assistance of air ejection from a plurality of sub-nozzles. The rollers are always driven to rotate during a weaving operation of the loom. A change-over device is provided to change the weft yarn from a first state of being put between the rollers to a second state of separating from the rollers or vice versa. The changing from the second state to the first state of the weft yarn is made after the starting of ejection of the fluid jet from the weft posture regulating nozzle in a weft picking cycle thereby preventing the weft yarn from being slackened in a location between the weft traction device and the weft posture regulating nozzle.

摘要： An air jet loom is equipped with a weft storage device for detaining a weft yarn prior to weft picking through a weft inserting nozzle. The weft storag device includes a roller reel on which the weft yarn is wound in the shape of a coil. The roller reel consists of a plurality of rollers arranged in the shape of a reel in which the axis of each rollers is outside any of planes containing an axis of the roller reel. Some of the rollers are driven around their axis. An engaging member is movably disposed in the vicinity of the unwinding end section of the roller reel and normally engaged with the weft yarn but disengaged from the weft yarn during weft picking, thereby sharply reducing weft picking resistance applied the weft yarn to be picked into the shed of warp yarns.
