Latest Patents

Colpitts 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 enhance the writing process of data onto optical discs. The invention includes an optimization circuit that generates a modulation signal to modulate a writing beam of a laser beam recorder. This optimized modulation signal consists of data symbols that correspond to pits and lands on the optical disc. The optimization circuit allows for individual adjustments of the leading and trailing edges of the data symbols, as well as their amplitudes. This capability enables the precise selection of pit and land lengths based on various factors, including their radial and angular locations on the disc. Additionally, the selective placement of these transitions can embed a second set of data for watermarks or anti-piracy codes. The invention also addresses electrical jitter errors through a master driver circuit that reclocks the initial modulation signal.
