Latest Patents

Kashimura holds a patent for a magnetic erasing head designed for erasing magnetic recording media, such as magnetic tape. This device features a head surface that makes sliding contact with the tape surface. The head surface incorporates both permanent magnet material and high permeability material. The permanent magnet material is strategically magnetized to create alternating polarities, with a field strength that gradually decreases from the inlet side to the exit side of the head surface. This design ensures that the magnetic tape erased by the head does not induce secondary harmonic distortion due to the mutual cancellation of residual magnetism.
