  • Method and apparatus for providing omnidirectional illumination using LED lighting
    Patent number: 8395310
    Abstract: A light-emitting device capable of generating omnidirectional light utilizing a reflector is disclosed. The light-emitting device, in one aspect, includes a light emitting diode (“LED”) package, a light reflector, and a shell. The LED package, which is mounted on a plate, generates a forward light cone by converting electrical energy to optical energy. The light reflector can be formed with various different shapes that can be placed adjacent to the LED package. A function of the light reflector is to redistribute at least a portion of the forward light cone whereby the overall light illuminated by the light-emitting device complies with LM79 specifications. The shell is used to enclose the LED package and the light reflector and configured to illuminate light in omnidirectional radiation in response to the forward light cone.

  • Magnetic disk drive and magnetic head slider with stabilized flying
    Patent number: 8270116
    Abstract: A magnetic disk drive includes a magnetic recording medium and a magnetic head slider adapted to fly over a surface of a magnetic recording medium and read or write information. The magnetic head slider includes a slider air bearing surface and a magnetic transducer. The slider air bearing surface includes a front pad having front rail surfaces and front step bearing surfaces, a rear pad having a rear rail surface and a rear step bearing surface, and a negative-pressure groove interposed between the front pad and the rear pad.

  • Head slider
    Patent number: 8218266
    Abstract: Embodiments of the present invention provide a slider that may suppress contamination from being attached to the flying surface of the slider without influence on reduction of the flying height of the slider. Ions exerting an effect of decreasing surface energy are implanted in the whole surface of a flying surface of a magnetic head slider except for a front rail surface and a center rail surface. According to this, contamination is prevented from being attached to a front step bearing surface, a side step bearing surface, a center step bearing surface and a negative pressure groove where contamination is particularly liable to be attached in the flying surface of the magnetic head slider, so as to suppress destabilization in flying of the slider.

  • Disk drive and head slider
    Patent number: 8102626
    Abstract: Embodiments of the present invention provide a head slider that suppresses accumulation of lubricant droplets on an air-bearing surface due to a backflow, and thus improves reliability of a disk drive. According to one embodiment, a lubricant droplet being adhered to a head slider and accumulated thereon, which are caused by extremely low flying height of the head slider, are prevented from falling onto a recording medium. When velocity of a recording medium at a position where the head slider faces the recording medium is assumed to be v, step depth ?4 at an outflow side of an outflow side rail satisfies, ?4?0.1125*log10(v)+0.019.
