  • Creating a sub-micron pattern proximate a near-field transducer using in-slider waveguide and laser
    Patent number: 9460746
    Abstract: An air-bearing surface of a slider is coated with a photoresist having a high optical absorbance at or near an operational wavelength of the slider. Light is directed at a target wavelength through an entry of a waveguide integrated into the slider. The light exiting the waveguide forms a feature through the photoresist, the feature proximate a near-field transducer of the slider. A sub-micron pattern is formed using the feature.
    Type: Grant

  • Slider cavity feature for gimbal attachment
    Patent number: 9196274
    Abstract: Disclosed is an embodiment of a suspension for a disk drive having a slider configured for bonding with a gimbal using an adhesive. Embodiments of the slider include one or more cavities in a portion of a slider mounting surface of the slider. The one or more cavities are configured for increasing a volume of the adhesive between the slider mounting surface and the gimbal. A method of forming the one or more cavities on the slider mounting surface, and bonding together the gimbal and the slider is disclosed.

  • Modular dice system for slider bar parting
    Publication number: 20030221309
    Abstract: The present invention relates to a dice system that is configured to manufacture disc drive heads from a substrate. The dice system includes a first dicing station that includes a plurality of processing modules. The dice system also includes a control module separate and distinct from the first dicing station. The control module is adapted and configured to control functions of the first dicing station modules and is further capable of being positioned at a remote location from the first dicing station.
