  • Controlling compressive force using pressure sensitive film
    Patent number: 7190440
    Abstract: A film is placed between contacting surfaces in an assembly. The film has an optical property responsive to pressure. A compressive force is applied to the contacting surfaces to generate an initial pressure pattern. The film is removed from between the contacting surfaces. The optical property is sensed to derive a sensed initial pressure pattern. A stored setting controls the compressive force. The sensed initial pressure pattern is compared to a reference pressure pattern. The stored setting is updated to adjust the compressive force as a function of the comparing.
    Type: Grant
    Filed: July 11, 2003
    Date of Patent: March 13, 2007
    Assignee: Seagate Technology, LLC
