摘要:
A head-gimbal assembly for suspending a magnetic head over a spinning disk in a magnetic disk drive having head suspension positioning apparatus includes a base plate fastenable to the positioning apparatus in the magnetic disk drive. a load beam coupled at one end thereof to the base plate and a first dimple in the load beam at another end thereof, a flexible gimbal coupled to the load beam near the other end thereof and a second dimple in the gimbal having a concave surface facing a convex surface of the first dimple and a convex surface to which the magnetic head is attachable. Preferably, the convex surface of the first dimple has a radius smaller than a radius of the concave surface of the second dimple. The head is attached to the gimbal by an adhesive material attached to the convex surface of the second dimple and a top surface of the magnetic head. The adhesive material is hardened while a bottom surface of the head and the base plate are held in a predetermined attitude relative to one another (e.g., parallel to one another). Preferably, a predetermined force is applied to the head-gimbal interface while the adhesive material hardens corresponding to (e.g., equal to) an operational force exerted on the head-gimbal interface during operation of the magnetic disk drive.

A gimbal embodying the present invention couples the magnetic head to the load beam through torsion fingers which twist to permit rotational motion of the head in one degree of freedom (e.g., pitch or roll) and bending arms which bend to permit rotational motion of the head in the other degree of freedom. Lateral separation of localized bending regions of the arms, and a dimple, serve to prevent motion of the head in other rotational and translational degrees of freedom.

A disc storage system includes a rotating disc and a transducer. The transducer is carried on a slider which is supported by an armature. The armature is used to move the slider radially across the disc surface whereby information may be read from or written to the disc surface of the transducer. The slider includes an air bearing surface which faces the disc surface. As the disc rotates, the air bearing surface causes the slider to “fly” over the disc surface. Pads are provided on the air bearing surface to improve operational characteristics of the system and texturing is provided to a landing zone region on the disc surface.

A method and apparatus is provided for accelerating the wear of gas lubricated surfaces that operate in intermittent contact. The method includes the generation of ultrasonic sound in the gaseous atmosphere surrounding the interface, and the further directing, focusing, or concentrating of said ultrasonic sound to impinge upon the gas bearing inlet. This method is capable of more accurate interface lifetime predictions than conventional methods, since, in contrast with conventional methods, the medial gas bearing properties, environmental parameters, and structural support conditions, present during testing, are unchanged from those present during typical operation. The present invention will also enable the evaluation of the effects of magnetic disk drive component design changes, in terms of head disk interface lifetime, even when a majority of the wear occurs during normal device operation and not during device starting or stopping. Conventional methods of wear acceleration cannot genuinely do this, and consequently distort the test results.

This document describes techniques and apparatuses enabling a proximity-dependent shopping offer. In some embodiments, the techniques determine, based on information about a user of a mobile device, that the user is likely to be interested in a particular product. The techniques may also determine that the user is conveniently near to a store at which to purchase the product. By so doing, the techniques enable stores to target offers to a person that is likely to be interested in visiting the store.

A safety release mechanism for snowboards functions with standard contemporary snowboarding boots and bindings. Bindings that would normally be fastened to the snowboard are instead both fastened to a single binding support platform. A platform retention assembly, fastened to the snowboard, includes preloaded compliant members that form interfaces with contours on the binding support platform. The interfaces prevent the binding support platform from separating from the snowboard except when a force or torque applied to the snowboard exceeds a set threshold. The platform retention assembly also includes firm features that contact firm mating features on the binding support platform to prevent translation of the binding support platform relative to the platform retention assembly in the plane of the snowboard. The firm features and the firm mating features are arranged such that the contacts between them, when projected onto the plane of the snowboard, are all tangent about one mutual center point.

摘要:
A disc drive is disclosed that includes textured features on the disc surface and a slider. The slider texture can include one or more features oriented in a first direction, and the disc can include one or more features oriented in a second direction. The first and second directions are selected such that the second direction includes a component that is perpendicular to the first direction. The orientation of the features facilitates the provision of matrix of contact points between the slider and the disc surface.
