Latest Patents
One of Ozawa's latest patents is for a reproducing stylus designed for an information signal recording medium. This innovative stylus traces a track of a recording medium, where an information signal is recorded as variations of geometrical shape. It reproduces the recorded information signal as variations in capacitance. The stylus features a main structure with a tip portion that has a sliding contact face, which slides along the track of the recording medium. An electrode is integrated into the stylus to trace the track and reproduce the information signal based on the variations in geometrical shape. The design includes specific features such as parallel side edges near the tip portion and a sliding contact face with a leading and trailing part.
Another notable patent involves a laser recording information system that records an information signal along with reference signals for tracking control. This system alternately records first and second reference signals of different frequencies on a recording disc, along with a third reference signal for switching between the first and second signals during reproduction. The reproducing system is capable of reproducing the information signal alongside the reference signals using a single reproducing element.
