Abstract: Methods for adhering parts together using part gap spacers are provided herein. Part gap spacers are formed in a selected pattern and a selected height on a surface of at least one surface of two parts to be oppositely disposed. When disposed opposite each other, at least some of the part gap spacers contact the opposite surface, and establish a standoff distance that is generally uniform, and thereby creating voids. Adhesive is disposed in at least some of the voids to adhere the part surfaces to each other. Further methods comprise forming part gap spacers on multiple sides of a third part to be disposed intermediate two surfaces. The part gap spacers can be formed in a variety of shapes, including bumps, tapers, ribs, and flange edges.

Abstract: A motor may include: a rotor case having a coupling hook extending downward in an axial direction, secured to a shaft, and performing rotation; a sleeve supporting the shaft; and a sleeve housing having a projection provided at a front end portion of an upper part thereof in the axial direction and a guide passage provided along the projection such that the coupling hook moves along the guide passage while the sleeve is pressed and inserted into an inner circumferential surface thereof.

Abstract: The invention relates to a spindle motor having a deep-drawn baseplate and an aperture to receive and secure a bearing system to rotatably support a rotor. To avoid having to machine the bearing receiving portion of the baseplate in a complex process, the invention provides for a separate bush to be disposed in the aperture in the baseplate to receive and secure the bearing system. Compared to the baseplate, this bush can be worked in a simpler and more cost-saving process.

Abstract: A grooved cam plate for vertically moving a roller as a crank pin is provided to move the roller vertically correspondingly to a movement of a movable table by slipping the roller in and slipping the roller up from the groove of the camp plate. A disk is reversed by the rotation of a chucking mechanism due to a half rotation of a crank shaft by the vertical movement of the roller.

Abstract: A storage device comprising a magnetic storage medium mounted in a first plane, a read and write mechanism mounted in a second plane that is parallel to the first plane and configured to write information to the magnetic storage medium, and a micromover configured to move the magnetic storage medium in a first direction parallel to the first plane and configured to move the magnetic storage medium in a second direction parallel to the first plane and perpendicular to the first direction.

Abstract: A motor of this invention is provided with a sleeve-type bearing impregnated with oil for supporting a rotor assembly including a shaft and a rotor member. A lower face of the rotor is provided with at least two peripheral wall portions, an inner peripheral wall portion and an outer peripheral wall portion, which surround the shaft with a gap therebetween in a radial direction. The peripheral wall portions are accommodated in an annular recessed portion so as to surround an open space over a sleeve constituted the sleeve-type bearing and has a lower top of the most inner part. The lower end of the inner peripheral wall portion is located lower than the lower end of the outer peripheral wall portion, and the lower end of the outer peripheral wall portion is located lower than the lower top of the annular recessed portion.

Abstract: A system for exchanging digital data among a plurality of hand-held computer devices. Digital signals are written by a first hand-held device to a mini-cartridge that mini-cartridge is inter-operable among a class of hand-held devices, each of which is equipped with a mini-disk drive. A common digital data format is employed to further facilitate exchange of data between devices.

Abstract: A read sensor and method of making the same using an etch-stop layer are disclosed. The method is particularly suitable in connection with techniques requiring the partial removal of the capping layer, such as exchange tab (ET) and lead overlay (LOL) techniques. Basically, a thin “etch-stop” layer is deposited over a top free layer of sensor materials. The etch-stop layer is made of a suitable material such as copper oxide (CuO) or nickel-iron-chromium (NiFeCr). A tantalum (Ta) capping layer is then deposited over the etch-stop layer. When appropriate, top edge portions of the capping layer are exposed to a reactive ion etch (RIE) using a fluorine gas for removal. Advantageously, the etch-stop layer significantly reduces or eliminates damage to the free layer that would otherwise occur due to the fluorine gas RIE.

Abstract: A disk drive receives a removable storage disk thereinto and has a frame and a disk motor helically mounted thereto for engaging the disk and applying a rotating force thereto. The motor has first threads integral therewith and the frame has second, mating threads integral therewith. The first and second threads interact to achieve helical movement.

Abstract: A disk recording system for disks such as videod isks or compact disks has a turntable on which the disk is supported adjacent a recording head. A shaft defining the axis of rotation of the turntable rotates in a bearing and that bearing is itself movable about an axis defined by another shaft. The bearing of the shaft is an air bearing and there is a damper unit for damping that movement. There may be a sensor for detecting the rate of rotation of the shaft defining the axis of rotation of the turntable. The radial displacement of the head relative to the axis of the turntable may be determined on the basis of rotation of the other shaft, and the rotation of the turntable controlled on the basis of the product of signals representing the radial displacement and the rate of rotation of the shaft, respectively.
