Latest Patents

Among his notable inventions is the dropout detection circuit and optical disc apparatus. This invention features a high-speed envelope detection circuit that analyzes the reflection signal of a light beam with a first time constant. Additionally, it includes a low-speed envelope detection circuit for the same signal, but with a second time constant that exceeds the first. A differential circuit generates a difference signal based on the outputs of both envelope detection circuits, while a comparator converts this difference signal into a binary value according to a specified criterion. An important aspect of this invention is the adjustment of the high-speed envelope detection circuit’s first time constant, which is extended during recording phases compared to reproduction phases, ensuring stable dropout detection in both scenarios.
