Title: The Innovative Contributions of Atsuko Motai
Introduction
Atsuko Motai is a prominent inventor based in Saku, Japan. She has made significant contributions to the field of optical recording technology. With a total of 5 patents to her name, her work has advanced the capabilities of optical media.
Latest Patents
One of her latest patents is an optical recording/reproducing method. This method involves an optical recording medium that comprises an organic dye base recording layer and a reflective layer on a resin substrate. The substrate features a groove of 1,100 to 2,300 Å deep, where signals are written by directing recording light to the recording layer from the back side of the substrate. This process occurs at a relative linear velocity of at least 3.6 m/s, resulting in record marks formed through partial decomposition of the dye while deforming the groove bottom surface. The deformation is minimized to less than 18% of the groove depth, allowing for a short recording time and reduced jitter during reproduction. Another notable patent is for an optical recording disk, which includes a substrate, a dye recording layer, a lower reflective lamina, an upper reflective lamina, and a protective coat. The lower reflective lamina is made from materials such as gold, platinum, silver, aluminum, or their alloys, while the upper reflective lamina consists of a stainless steel composition or an alloy with a significant copper content. This design ensures reliability and cost-effectiveness.
