Latest Patents

Hara holds a notable patent for a magnetic recording medium and its manufacturing method. This innovative design includes a magnetic recording medium with a high recording density, which consists of a first ferromagnetic layer, a non-magnetic layer, and a second ferromagnetic layer. These layers are successively deposited on a non-magnetic substrate, enhancing the performance and storage capabilities of magnetic media. The recording layer undergoes heating in concentric circular shapes, effectively dividing it into regions characterized by either ferromagnetism or anti-ferromagnetism. This clever differentiation allows the ferromagnetic regions to serve as recording tracks, while the anti-ferromagnetic regions function as guard bands, leading to increased track density without compromising the surface quality of the recording medium.
