Latest Patents

One of her latest patents is for an optical recording disc. This invention features a disc substrate made of a synthetic resin with light transmittance. It includes a hub made of synthetic resin, which is fixed to the center part of the disc substrate using techniques such as supersonic wave expansion molding. Additionally, a circular magnetic metal plate is installed through insert molding. A continuous circular groove is also incorporated at the outer peripheral side of the fixing part between the disc substrate and hub. This groove is designed to absorb stress generated by differences in thermal expansion rates between the disc substrate and the magnetic metal plate.

Another notable patent is for an optomagnetic recording medium. This medium utilizes both rare earth metals and transition metals within the optomagnetic recording system. The recording medium consists of 15 to 35 atomic % of rare earth metals such as gadolinium (Gd), terbium (Tb), or dysprosium (Dy), with the remainder being an alloyed mixture of iron (Fe), cobalt (Co), and germanium (Ge). This innovative material has an increased phase transition temperature without raising its Curie point, allowing for effective recording and erasing under high-temperature conditions.
