  • Near-field objective lens for an optical head
    Patent number: 6844983
    Abstract: A near-field optical head objective lens that can read and write high-density data on an optical disc is disclosed. On a surface where an incident beam converges by the near-field optical head objective lens, a film that can produce surface plasmon effect is coated. As the incident beam hits the material and produces the surface plasmon, a micro aperture is generated to minimize the diameter of the light spot, thereby increasing the data capacity stored in the optical disc.
    Type: Grant
    Filed: July 15, 2003
    Date of Patent: January 18, 2005
    Assignee: Industrial Technology Research Institute
