Latest Patents

Carson holds a patent for an invention titled "Individual adjustment of pit and land transition locations in an optical disc mastering process." This patent describes an apparatus and method designed to improve the writing of data onto optical discs. The invention includes an optimization circuit that generates a modulated signal to enhance the writing process. This signal comprises a series of data symbols that correspond to pits and lands on the disc. The optimization circuit allows for individual adjustments of the leading and trailing edges of these data symbols, as well as their amplitudes. This capability enables precise control over the length of each pit and land, taking into account various factors such as radial and angular locations. Additionally, the selective placement of these transitions can embed secondary data for purposes like watermarking or anti-piracy measures. The invention also addresses electrical jitter errors through a master driver circuit that reclocks the initial modulation signal.
