摘要： A method adjusts a flying-height distance between a magnetic write head and a magnetic medium. The method includes positioning the write head in a location spaced from the magnetic medium by the flying-height distance. The write head includes a magnetic yoke and a proximal region in proximity to the magnetic medium. The write head further includes a resistive heater and at least a portion of the resistive heater is within the magnetic yoke and is in proximity to the proximal region. The resistive heater is configured to heat the proximal region. The proximal region has a coefficient of thermal expansion. The proximal region is configured to expand and to contract in response to a temperature of the proximal region. The method further includes flowing an electric current through the resistive heater. The method further includes controlling the electric current to adjust the temperature of the proximal region to selectively expand and contract the proximal region and thereby control the flying-height distance. Controlling the electric current includes pulsing the electrical current and adjusting a time interval between pulses.

摘要： A method and apparatus for embedding a chip in a substrate to form a composite air bearing surface. An example of the method includes securing the substrate in a fixed position, aligning the chip in a first direction with a chip receiving slot in the substrate, depositing adhesive in the chip receiving slot, and aligning the chip in a second direction with the chip receiving slot. The chip is pushed into the adhesive in the chip receiving slot until the air bearing surface of the chip is substantially at a desired protrusion in a third direction in relation to the air bearing surface of the substrate. The adhesive is cured with the air bearing surface of the chip substantially at the desired protrusion in the third direction, and with the chip substantially aligned in the first and second directions with chip receiving slot.

摘要： A simple method of manufacturing a magnetic head having a head face and including a planar magnetic coil (7) which extends parallel to the head face. According to the method, the magnetic coil is formed at a first side of a first substrate (1). Thereafter, the first substrate provided with the magnetic coil is adhered with its first side to a side of a second substrate, whereafter material of the first substrate is removed from a second side of the first substrate (9), the second side being turned away from the first side, in order to form the head face, in such a manner that the magnetic coil is situated near to the head face.

摘要： A method of burnishing a rear pad of a slider within a disk drive. The rear pad is formed of a burnishable material and maintains elements for reading and writing. The disk drive further includes a spindle motor rotatably driving a disk and an actuator assembly positioning the slider over a surface of the disk. With this in mind, the method includes rotating the disk. The slider is moved in a radial fashion relative to the disk surface in a reciprocal fashion, causing the rear pad to rock. As the rear pad rocks, contact between the rear pad and the disk surface burnishes the rear pad. As a result, a positive camber is imparted in the rear pad relative to the MR element. The above-described method can be practiced following initial manufacture of the disk drive, or at various times over the life of the disk drive. Regardless, the method is practiced in-situ and is therefore very fast, cheap, and adapts quickly to the particular disk in which the slider is flying.

摘要： A tape head assembly for high-speed and high-density multi-channel read-while-writing (RWW) operation comprises two modules bonded together. The modules are initially formed on an integral unit and gapped in pair, to produce a good reference surface, which insures that the finished head assembly will meet tight azimuth and gap tolerances. The unit is then machined to two separate the modules. Further processing involves individually machining the head surface of each module to achieve desired contours. The machined modules are tested and brought together in the positional arrangement required to form the final head assembly. In disclosed embodiments, the overall contour enables the assembly to skive air and debris off a surface of the magnetic tape before passage of the tape over the transducers. The contour allows the tape to fly over outriggers, but contacts regions at or around the transducers with a low constant contact pressure during RWW operation.

摘要： A magnetic disk apparatus includes a magnetic disk, a magnetic head for writing data into and reading data from the magnetic disk, a carriage pivoted on a pivot bearing while holding the magnetic head at its one end, the pivot bearing being constituted by a cylindrical sleeve serving as a fixed axle, bearing units each having an outer race fitted to the inside of the sleeve, bearing balls, and an inner race, and a shaft having the outside fitted to the inner races of the bearing units, thus, change of a pre-load caused by a heat expansion difference between the shaft and sleeve is an axial direction is compensated with a change of a pre-load caused thereby the same is a radius direction. Hence, the weight of a pivotally movable portion of an actuator is reduced.
