Latest Patents

Horiguchi holds a patent for a magneto-optical recording medium. This medium allows for direct overwriting by modifying the power level and/or pulse width of applied optical pulses, without changing the direction of the bias magnetic field. The recording layer consists of first and second magnetic recording layers. The first magnetic layer is a rare-earth transition metal-amorphous alloy with a perpendicular easy magnetization axis, a thickness ranging from 10 to 200 nm, and a compensation temperature above room temperature. The second magnetic layer is an alloy of cobalt and/or iron combined with a rare earth metal and/or a noble metal, or an alloy of cobalt with at least one metal selected from titanium, chromium, manganese, copper, zinc, gallium, and germanium. This layer has an in-plane easy magnetization axis and a thickness of no more than 3 nm.
