摘要： A magnetic recording disk drive uses side-by-side read/write heads formed on head carriers that are substantially identical for both top and bottom disk surfaces. Thus, a common head carrier functions as a single manufacturable part usable for both top and bottom disk surfaces. The common head carrier has a trailing end with a pattern of components formed on it that includes three side-by-side transducers and sets of terminal pads. In the read/write/read side-by-side head arrangement, the first element is a center write element, such as an inductive coil, and the second and third elements are read elements, such as magnetoresistive read elements, that are generally equally spaced from the center write element. In common carriers to be used for the top disk surfaces, one of the read elements is electrically connected to the read/write channel of the disk drive, and in common carriers to be used for the bottom disk surfaces, the other read element on the common carrier is electrically connected to the read/write channel. The disk drive thus operates in cylinder mode with side-by-side heads using a common carrier for both top and bottom disk surfaces.

摘要： A magnetic recording disk drive uses side-by-side read/write heads formed on head carriers that are identical for both top and bottom disk surfaces. Thus, a common head carrier functions as a single manufacturable part usable for both top and bottom disk surfaces. The common head carrier has a trailing end with a pattern of components formed on it that includes three side-by-side transducers (two read elements equally spaced about a center write element) and five terminal pads, one of which is a common pad, and all of the electrical connectors interconnecting the five terminal pads with the three transducers. There are only three terminal pads for the two read elements, with one of the read terminal pads being a common terminal pad that is electrically connected to both read elements. During assembly of the disk drive, the common carrier, when used as the top carrier, has a first read terminal pad and the common terminal pad connected to the leads on the suspension. When used as the bottom carrier, the second read terminal pad and the common terminal pad are connected to the leads on the suspension. Thus, only one carrier common to both top and bottom sides of the disk needs to be manufactured. The uniqueness of the top and bottom carriers is obtained by the wiring connection of the read terminal pads to the leads on the suspensions.

摘要： A new method for making patterned magnetic storage media with magnetic and substantially non-magnetic zones utilizes a selective oxidation processes. Selective oxidation is achieved by subjecting a magnetic layer to an oxygen plasma through voids in a patterned mask. A high resolution patterned mask is made by embossing and reactive ion etch processes. The method is used to fabricate patterned magnetic disks media with alternating magnetic and non-magnetic zones ranging from 10 to 1000 Nanometers in width. Magnetic storage disks produced by this method have high-bit densities, minimal topography and reduced signal noise.

摘要： The present invention is a magnetic head having a helical induction coil and includes hard disk drive devices that utilize the magnetic head. The helical coil is fabricated around a magnetic pole yoke in a series of process steps that include a reactive ion etch (RIE) process step which is utilized to simultaneously form vertical interconnect vias and upper helical coil member trenches. Thereafter, in a single fabrication step, such as by electroplating, the vertical interconnect lines and the upper helical coil traces are created in a single fabrication step, such that they are integrally formed. The vertical interconnect lines provide an electrical connection between outer ends of previously formed lower helical coil traces and outer ends of the integrally formed upper helical coil traces, such that a helical coil is fabricated. In the preferred embodiment, the helical coil is composed of copper.

摘要： A suspended resist bridge suitable for lithographically patterning MR sensors having trackwidths narrower than 0.2 micron is fabricated using the method of the present invention. First, PMGI is spun onto a substrate to form a first thin resist layer. Next, PMMA is spun onto the first resist layer to form a second resist layer. The PMMA layer is exposed to an electron beam to pattern the trackwidth of the MR sensors. E-beam exposed PMMA is then developed in an IPA solution. The resist structure is then placed in a basic solution for dissolving PMGI, which results in a fully undercut resist bridge that is used for patterning the MR sensors.

摘要： A read/write head is provided with an embedded planar dual coil write structure. The head includes generally parallel shield, shield/pole, and pole layers. The shield/pole layer abuts a generally coplanar planarization layer in one embodiment. A circuitous recess is defined in the shield/pole and planarization layer, spanning the junction twice and encircling a central hub of adjoining shield/pole and planarization layer material. A write structure is located in the recess, with the shield/pole layer, planarization layer, and embedded write structure forming a substantially flat surface for building the pole layer. The write structure includes first and second substantially co-planar multi-turn flat coils, where turns of the first write coil are interspersed with turns of the second write coil. The first and second write coils reside in the circuitous recess, winding around the central hub. An insulating material separates the first and second coils.

摘要： A magnetic tunnel junction (MTJ) magnetoresistive read head for a magnetic recording system has the MTJ sensing or free ferromagnetic layer also functioning as a flux guide to direct magnetic flux from the magnetic recording medium to the tunnel junction. The MTJ fixed ferromagnetic layer and the MTJ tunnel barrier layer have their front edges substantially coplanar with the sensing surface of the head. Both the fixed and free ferromagnetic layers are in contact with opposite surfaces of the MTJ tunnel barrier layer but the free ferromagnetic layer extends beyond the back edge of either the tunnel barrier layer or the fixed ferromagnetic layer, whichever back edge is closer to the sensing surface. This assures that the magnetic flux is non-zero in the tunnel junction region. The magnetization direction of the fixed ferromagnetic layer is fixed in a direction generally perpendicular to the sensing surface and thus to the magnetic recording medium, preferably by interfacial exchange coupling with an antiferromagnetic layer. The magnetization direction of the free ferromagnetic layer is aligned in a direction generally parallel to the surface of the medium in the absence of an applied magnetic field and is free to rotate in the presence of applied magnetic fields from the medium. A layer of high coercivity hard magnetic material adjacent the sides of the free ferromagnetic layer longitudinally biases the magnetization of the free ferromagnetic layer in the preferred direction.

摘要： A disk drive assembly in which the suspension and read/write transducer are integrated into a combination assembly and fabricated using thin film deposition techniques thereby producing an assembly which is very low in mass permitting contact recording. In one embodiment, transducers are deposited in a row and column configuration onto a release and support layer covering a wafer substrate having a thickness equal to a desired suspension length. The wafer is separated into a plurality of row sections, with each row section providing one thin film transducer from each column. A second release layer is formed on a separated side on the row section and thin layers of suitable materials are deposited to form a suspension layer including conductive lines extending to the thin film transducers. The first and second release layers are dissolved and the row section is further cut to form the individual combination assemblies. In a second embodiment, the wafer substrate has a thickness equal to the width of the suspension. The transducers deposited on a row are separated by the desired suspension length to produce combination assemblies useful for linear disk drive actuators. The excess portion of the wafer substrate can alternatively be removed by cutting or etching eliminating the requirement for release or support layers.
