发明名称 Magnetic head
摘要 There is disclosed a magnetic head constructed with a core formed by butt-connecting a plurality of core halves, each having different magnetic flux density or magnetic permeability, and a winding wound around the core, wherein an intense magnetic field is created at the butt-connected portion. One of the core halves has a high magnetic permeability and the other has a high magnetic flux density so as to improve both the output characteristic and reproduction sensitivity of the magnetic head. Further, the core half having a higher magnetic flux density than the other is disposed at the side where a recording medium in motion leaves the head so that a satisfactory recording and erasing magnetic field may be imparted to the recording medium such as metal tape. Furthermore, the core is constructed with a combination of high hardness permalloy having different magnetic flux or magnetic permeability, or a combination of such high hardness permalley and sendust so as to reduce manufacturing cost of the magnetic head.
