Latest Patents
One of Heikichi Sato's latest patents involves a magnetic head designed to improve the interaction with magnetic recording media. This innovative magnetic head features a sliding surface where the magnetic recording medium is positioned. It includes a magnetic gap formed in the sliding surface for exchanging information signals. The design incorporates a track width controlling portion that prescribes the track width of the magnetic gap. This portion is created by abutting a pair of magnetic core halves together, which have track width controlling grooves formed in each half. Additionally, metal magnetic films are associated with the magnetic gap and the track width controlling portion. A unique groove is also formed at one end of the magnetic gap, extending parallel to the sliding direction of the magnetic recording medium. The relationship between the length of this groove and the intensity of the recording current is defined by a specific mathematical expression. This innovative design helps prevent demagnetization in the recording track of magnetic tape.
