  • Non-contact optical glide tester
    Patent number: 5818592
    Abstract: A non-contact optical method and apparatus for use in inspecting and measuring defects on a disk. The apparatus generates an interference pattern from a reference beam reflected from a surface of a transparent slider with a second beam reflected from a surface of a test disk. The resulting interference pattern is processed by a set of photodetectors and processing electronics to quantify and map the location and magnitude of asperities on the disk.
