Latest Patents
One of Akiyoshi Ito's latest patents is a method for recording and reproduction on a magneto-optical recording medium. This invention provides a solution for reproducing information recorded by multi-valued recording at a high signal-to-noise (S/N) ratio. The patent describes a magneto-optical recording medium that includes two magnetic layers capable of four-valued recording based on four combined magnetization states. The reproduction signals concerning the four magnetization states differ depending on the wavelength used during reproduction. The two magnetic layers are irradiated with light beams of different wavelengths, allowing for the extraction of two-valued or higher multi-valued reproduction signals. These signals are then logically processed to reproduce the recorded information effectively.
