Clark N Kurtz is a notable inventor based in Rochester, NY (US), recognized for his contributions to magneto-optic technology. With a total of 8 patents to his name, Kurtz has made significant advancements in methods and apparatuses that enhance data recovery from magneto-optic recording elements.

Latest Patents

Among his latest patents is the "Magneto-optic readout method and apparatus using polarization switching." This invention describes a method for recovering information from a vertically magnetized magneto-optic recording element. The process involves operating a laser in a state of polarization instability, where its TE and TM losses are equal. The laser's output is converted to circularly polarized radiation, which is then used to scan the recording element. The reflected radiation is reconverted to linear polarization, allowing for the detection of the instantaneous polarization mode of the laser. This mode indicates the orientation of the magnetic domains scanned by the laser radiation. Another significant patent is the "Magneto-optic readout apparatus using polarization switching of readout." This apparatus plays back information from a recording layer that exhibits different light absorption characteristics for left and right circularly polarized beams emitted from a laser. The laser operates in two different polarization modes, and the system is designed to switch modes based on the magnetic orientation of the medium.
