  • Laser assisted track width definition and radial control with magnetic recording
    Patent number: 7518827
    Abstract: The present invention provides for the enhancement of the storage capacity of a data disk drive while reducing optical path optics, electronics and/or the mass and complexity of associated read/write heads. The system utilizes light transmitted by optical elements to servo track a data disk and to heat the data disk during reading and writing of data, and magnetic elements for actual reading and writing.
    Type: Grant

  • Liquid immersion lens for optical data storage
    Patent number: 6084846
    Abstract: A slider for an optical read head includes a liquid-immersion-lens between an objective lens and an optically transparent base of the slider. The liquid-immersion-lens includes a high index of refraction liquid, thereby eliminating a lens-air interface at the lower surface of the objective lens. The liquid-immersion-lens provides for the production of a small light spot at the surface of the optical disc.
