摘要： Write heads and corresponding methods of fabrication are provided using multiple electronic lapping guides to collect information regarding multiple distances of a write head, such as a throat height and a flare point distance of a write pole. A method of fabricating a write head includes fabricating a write pole and a corresponding write pole ELG. The method further includes fabricating a trailing shield and a corresponding trailing shield ELG. The method further includes performing a lapping process on the write head, and monitoring a lapping depth of the lapping process based on the resistance of the write pole ELG and the resistance of the trailing shield ELG.

A first barrier layer is located between the emitter region and the base region, and a second barrier layer is located between the collector region and the base region. A plurality of terminals of the TTM include a base lead coupled to the base region, a collector lead coupled to the collector region, and an emitter lead coupled to the emitter region. The collector region is or includes a layer of semiconductor material. The base region includes a free layer structure. The TTM further includes a self-pinned layer structure and an in-stack longitudinal biasing layer (LBL) structure formed in stack with the sensor stack structure, with a magnetic moment that is parallel to a sensing plane of the TTM for magnetically biasing the free layer structure.

摘要： A method and apparatus for forming a high conductance, high aspect ratio structure in a single low temperature copper chemical vapor deposition step. A trench for a winding of a coil is formed by forming a first length of the trench in the insulation layer. The first length of the trench forms a first portion of the winding of the coil in a confined area proximate a yoke region. A second length of trench is formed in the insulation layer extending away from the first length of the trench and the yoke region. The second length of trench includes parallel trenches for forming a second portion of the winding in a nonconfined area. A metal is deposited into the first length of the trench and the second length of the trench to form the first and second portions of the winding of the coil.

摘要： A slider having a lead circuitry configured to minimize capacitive coupling between leads in a slider having a read head, a write head and an extra device such as a heater element. The leads are configures so that wherever a pair of leads cross one another, they do so at right angles or at nearly right angles. The leads can cross one another at angles of between 45 and 135 degrees, but preferably cross one another at an angle of about 90 degrees. The leads are electrically insulated from one another by a dielectric material formed between them. By crossing a pair of leads at right angles to one another, the overlapping area between the leads is minimized, thereby minimizing the capacitive coupling between them.

摘要： A system and method for controlling the position of a digital data storage device slider through the use of an electro-thermal micromechanical actuator is disclosed. A movable member is etched into a face of a slider opposite the air-bearing surface of the slider. The movable member is substantially freestanding in relation to the slider, having only a single end connected to the slider. An electrically actuated heater element with two parallel current paths is disposed on the movable member. One of the current paths is substantially narrower than the other current path. When a current is passed through the heater element, the narrower current path heats up more quickly than the wider current path. By varying the current passed through the heater element in a selected manner, a distortion of the movable member is harnessed and used to create a relative motion in the slider body, allowing the slider to be quickly and exactly located over the centerline of a track of a storage device.

摘要： A magnetic head having a magnetic pole that includes a pole tip and a yoke. The pole tip includes an elongated neck, having an anchor piece on one end and a yoke interconnection piece on the other end. The air bearing surface of the head is located approximately at the midpoint of the elongated neck, and shadowing effects of the end pieces during the ion milling notching process do not create significant variations in the width of the neck at locations near the midpoint of the neck. As a result, variations of the pole tip width at the ABS of fabricated magnetic heads is significantly reduced, and processing yield is therefore increased. The yoke is engaged to the pole tip at a location along the neck that is close to the air bearing surface. In a preferred embodiment, the yoke interconnect piece is encapsulated within the yoke.
