Latest Patents
One of Drutowski's latest patents is titled "Guided Servo Writing for Data Storage Media." This invention presents techniques for marking data storage media and responding to disturbances in the marking process. In one embodiment, the invention describes a system that utilizes a laser to emit a beam to ablate physical marks in a data storage medium. The system includes a sensor, such as an optical sensor, configured to detect the position of the data storage medium and generate a position signal based on its position. An optical device, controlled by an actuator, directs the laser beam to an ablation site on the data storage medium according to the position signal.
Another significant patent is "Tape Edge Monitoring." This invention determines the position of one or both edges of tape, such as magnetic tape, using a light source, like a solid-state laser with a collimated beam, and a detector, such as a photodiode. The tape blocks a portion of the light, affecting the amount of light reaching the detector. The detector generates signals based on the tape's position. When two detectors cooperate to measure the positions of opposing edges of the tape, the signals can be processed to produce at least four useful signals, including one that indicates the tape width and another that indicates the position of the tape centroid.
