Magnetic head for floppy disc drive and driving method

Abstract

Abstract PURPOSE:To obtain a magnetic head for floppy disc drive, which has a simple constitution and reduces damage of the surface of a medium during driving, and a driving method using this head by arranging magnetic heads provided on both faces so that they face each other on the same cylinder. CONSTITUTION:A conventional slider is eliminated to constitute a magnetic head 21 essentially with a magnetic pole 22 formed with an E core 22a and an R/W core 22b and a gimbals, and reinforcing materials 23 are attached for the purpose of enhancing the mechanical strength if required. Reinforcing materials 23 consist of, for example, bar-shaped ceramic materials reinforcing junction parts between the gimbals 24 and the magnetic pole 22, and it is unnecessary to bring them closely into contact with the whole of the magnetic pole conventionally. Therefore, it is unnecessary to polish side faces of the E core into specular surfaces, and the working process of the magnetic head is simplified, and only the core is brought into contact with the medium. On the other hand, peripheral parts of the face, which is brought into contact with the surface of the medium, of the magnetic pole 22 are chamfered as shown by 26 and 27 in the figure. Thus, pointed parts are eliminated in the part of the magnetic head brought into contact with the surface of the medium, and the medium is not damaged.
