Abstract: The invention relates to an ambient light electrophoretic display comprising a plurality of cells containing a suspension of charged pigment particles in a light-transmissive fluid. Each cell comprises a light-transmissive front window, a nonobstructing collecting electrode and counter electrode disposed in the cell, and a panel having a reflective or absorbing surface.

Abstract: A method and apparatus for detecting and measuring organic materials present on components used in magnetic storage systems, such as an actuator coil. The component is heated on a hot plate, and a concave lens with a low surface energy coating is placed over the component. The contaminants volatilize and condense on the glass lens. The condensate is collected in solvent. The solvent is evaporated and the size of the residue is measured. A determination can be made whether the component is suitable for used in a magnetic storage system.

Abstract: A contaminant reduction system is shown for a disk drive assembly having a closed interior and slider disk components located therein which would be adversely affected by condensed volatiles generated within the assembly. A Peltier element is located within the closed interior of the disk drive assembly so as to condense volatiles present within the interior at a desired condensation point within the closed interior. A getter material, such as a microporous sintered alumina, is located within the closed interior of the disk drive assembly at the condensation point for permanently trapping and maintaining condensed volatiles which are condensed by the Peltier element.

Abstract: The invention relates to an improved high performance magnetic recording device. The recording device comprises a magnetic recording disk, a slider having a transducer for reading or writing data on the disk, a motor operable to rotate the disk at speeds greater than 7000 RPM and an actuator connected to the slider to move the slider across the disk. The trailing surface of the slider is coated with a low surface energy film to prevent build up of droplets of liquid contaminants.
