  • Patent number: 6643106
    Abstract: An intermediate article of manufacture of a magnetoresistive head with a protective device having sensor elements with terminal pads and a shunt element connected across the sensor element for shunting the sensor element to discharge static electrical charge during the manufacture of the magnetoresistive head. The shunt element is a piece of solder extending between the first and second terminals.

  • Patent number: 6639761
    Abstract: A micro-actuator including a skeleton having flexible beams, a rotor portion, a stator portion, and a damping material. The flexible beams connect the rotor portion to the stator portion and the damping material is applied to the skeleton. The damping material provides a protective layer to the flexible beams of a micro-actuator. The damping material increases the damping characteristics of the micro actuator and limits the penetration of humidity into the skeleton of the micro actuator.

  • Patent number: 6603637
    Abstract: Techniques are disclosed for improving the tribology between an air bearing surface of a magnetic recording head and a magnetic recording medium. In addition, techniques are described for reducing resistance to wear and corrosion of the air bearing surface of the recording head as well as resistance to corrosion of the recording medium. Various ion beam techniques can be used to enhance the properties of the recording head and recording medium, and include ion implant techniques, ion mixing techniques and ion burnishing techniques.

  • Patent number: 6536265
    Abstract: The present invention includes the realization that air bearing surface (ABS) microtexturing (i.e., the production of well-defined texture patterns on an ABS) affords an effective method to control the size of the apparent area of contact during head-to-disc frictional interaction, and thus provides a method to effectively prevent excessive friction force build-up which can lead to catastrophic tribological failure (head crash) during the glide characterization of super-smooth media for high areal density (for example greater than 20 Gb/in2) head-to-disc interfaces (ADIs).

  • Patent number: 6499881
    Abstract: A system for keeping the imperfectly machined surfaces of bearings apart at rest. The system includes a first bearing surface which moves facing a second bearing surface, the first surface having a distribution of discrete diamond-like carbon (DLC) pads deposited upon an adhesion layer. The DLC pads are at a height which is approximately the height of the roughness or imperfections of the surfaces. The pads are distributed over the surface at approximately three pads to forty pads or more per square inch. The pads keep the bearing surfaces from coming in contact. Also disclosed is a hydrodynamic bearing having a thrust plate having hydrodynamic grooves and DLC pads on a thrust surface, and a rotor member having an end facing the thrust plate, and a ball and socket bearing having DLC pads deposited on either the socket surface or ball surface.

  • Patent number: 6269687
    Abstract: A disc drive test slider apparatus for measuring contact force with a surface of a rotating disc media includes a slider body positioned proximate the surface of the rotating disc. The slider body includes an air-bearing surface substantially parallel to the surface of the disc and separated from the surface of the disc by a glide height. A cavity is formed in the slider body having a side wall substantially normal to the surface of the disc and a wall substantially parallel to the surface of the disc. A beam flexure is attached to the side wall of the cavity. A plate is attached to the beam flexure in the cavity, the beam flexure having a spring resiliency to permit movement of the plate in the cavity substantially normal to the surface of the disc. A contact rod is attached to the plate, and extends through the cavity and a via in the slider body. The contact rod has a distal tip projecting from the air-bearing surface.

  • Patent number: 6212042
    Abstract: 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.
