摘要： Methods of making a magnetic recording device with an “anchored” conductive stud which is securely attached within its surrounding insulator materials. The conductive stud is formed over a conductive layer which is coupled to or part of a read or a write head element of the magnetic recording device. The conductive stud has a top stud portion and a bottom undercut portion formed over the conductive layer. In one illustrated embodiment, the bottom undercut portion has a width that is greater than the width of the top stud portion. Since an insulator is formed around the conductive stud and over its bottom undercut portion, a secure coupling between the conductive stud and the conductive layer is provided. Preferably, the conductive layer is made of copper (Cu), the conductive stud is made of gold (Au), and the insulator is alumina (Al2O3). A seed layer may be formed between the conductive stud and the conductive layer.

摘要： A process for directly debonding sliders during single slider processing includes placing the sliders in pockets in a divider with one surface of each slider contacting a tape. A planerization material encapsulates the portions of the sliders which are not in contact with the tape. The planerization material is cured and the assembly is bonded to a process carrier. After ABS are etched into the sliders, the sliders are debonded by heating, cleaned, and inspected. The divider is removed from the carrier with the sliders still attached to the divider by the planerization material. The divider is then sandwiched between two lids to form a shim stack to enhance removal of the planerization material. The planerization material is removed in a hot solvent ultra-sonic bath and the lids are then removed for additional cleaning and inspection of the sliders.

摘要： An arbitrary gap thin film magnetic recording head is fabricated by forming a substrate based on traditional vertical planar thin film head wafer technology which is designed to produce an integrated subgap and subpole substrate structure. The wafer is then processed into row bars to reveal, in a plane parallel to the transducing direction of the medium, the subgap and subpoles at the surface of the row bar and to bring the structure to a certain coil depth or gap depth. A flat or cylindrical contour may be utilized. This thin film subgap row bar is taken through a film deposition or growth process that deposits the magnetic film on a plane perpendicular to the wafer plane, horizontal planar processing, forming a surface film recording head where an arbitrary gap structure can be made in-between the subpoles and generally directly on top of the subgap. The surface thin film is deposited and patterned on the tape bearing surface of the head to optimize various element configurations, gap patterns and head-to-tape medium contact. An arbitrary gap thin film magnetic recording head is manufactured using two major thin film processing planes, one orthogonal to the other, the first major plane is wafer level and the second major plane is sub-wafer level and perpendicular to the first. The first major plane of processing defines the magnetically active substrate including coils, subgap and subpole members. The second major plane of processing defines the surface film which transmits the flux from the subpoles to the gap features contained in the surface film. This resulting structure is a recording head that is wired to the servo system electronics and will format the tape with the arbitrary gap pattern.

摘要： A dual actuator arm assembly system that uses two pairs of actuator-carriage arms that linearly move over a stationary micro-rail independently. The geometric shape of the two pairs of actuator carriage arms conform to the arcs of the data tracks at an acute angle. System enables micro-actuation that is integrated to actuator arm and is a function of its geometry. Uninterrupted data stream and sector coverage and thus parallel data transfer scheme is made possible. Each actuator move only within a limited range of disk area, thus precision is increased, vibration is minimized and external transfer rate is speeded up and overall access time is shortened. Instant access to two quarters of the disk with two pairs of actuators and to park these without landing the heads—by positioning and constant fly height during idle mode, or when system is turned off, are introduced as what are new in the art.

摘要： The present invention relates to a magnetic thin film, which has high saturation magnetic flux density Bs of 2.2T or more, which is formed into a flat surface having surface roughness of 5 nm or less and which is capable of preferably being used for a write-head, and a magnetic head. The magnetic thin film includes a FeCo-based alloy layer stacked with a different layer so as to obtain the surface roughness of 5 nm or less. When forming the FeCo-based alloy layer, it is possible to flatten the film surface by performing reactive spattering using a reaction gas such as N2 for each of the layers forming the multi-layered thin film.
