Latest Patents
One of Shohei Kawasaki’s notable inventions is the "Adaptive Bias Control for Magnetic Recording Head." This patent describes a read head comprising a permanent magnet (PM) layer created up to 100 nm behind a free layer. The PM layer's magnetization can be initialized in a direction that adjusts the bias point of the free layer, thereby shifting sensor asymmetry closer to 0% for individual heads at the slider or Head Gimbal Assembly level. This improvement significantly enhances device yield by adjusting asymmetry with various initialization schemes and directions, tailored based on prior measurements. Notably, the PM layer can be made from CoPt or CoCrPt materials, with coercivity ranging from 500 Oersted to 1000 Oersted.
Another key invention is the "Magnetic Flux Guiding Device with Spin Torque Oscillator (STO) Film Having Negative Spin Polarization Layers in Assisted Writing Application." This patent reveals a STRAMR structure featuring a spin torque oscillator (STO) device integrated within a flux guiding layer that possesses negative spin polarization. This inventive configuration ensures that the magnetization almost aligns parallel to the magnetic field without current bias, enhancing functionality and performance in magnetic recording devices.
