Latest Patents
One of Nakamikawa's latest patents is a magnetic transfer method and apparatus. This invention involves bringing a master medium and a slave medium into close contact while applying a transfer magnetic field. The leakage magnetic field intensity is regulated to ensure the transfer of an exact magnetic pattern. Additionally, a magnetic field is applied to the slave face to initially magnetize it in the track direction before the transfer occurs. The method ensures that the magnetic field intensity component in the opposite direction is kept below the magnetic coercive force of the slave medium, allowing for precise magnetic transfer.
Another significant patent is for a flexible magnetic recording medium. This medium consists of a non-magnetic layer and a magnetic layer made of ferromagnetic powder dispersed in a binder. The ferromagnetic powder has specific coercive force and thermal fluctuation parameters, ensuring the formation of a magnetization pattern that represents predetermined information on the magnetic layer.
