Abstract: A composite magnetic head tip has a pair of head cores (2,3) facing each other and each having a center core (5,7) and a side core (4,6) which are separated by a magnetic gap (8,9) and are glass welded together at an apex portion (32). Each head core has a set of notches (14,14') which define a track width in the magnetic gap. Each notch is formed so that it begins at a confronting surface (29) where the center cores face each other, crosses through the magnetic gap, and ends on a sliding surface (28) for slidably contacting a magnetic medium. The notches end at a point which is directly above the welded position (19) provided at the apex portion of each head core.

Abstract: A compound type magnetic head comprising a main core (11) made of a magnetic material high in saturation flux density and low in inherent resistance, such as sendust or amorphous material and two auxiliary cores (12) sandwiching the main core (11) therebetween. The auxiliary cores (12) each consist of a first member made of a material high in inherent resistance such as ferrite and a second member made of a low melting point glass portion 42 formed on the front side of the first member, namely on the side abutting against the magnetic tape.

Abstract: A magnetic recording and reproducing head arrangement utilizing the azimuth recording method which has an even number 2n of magnetic heads mounted in the head assembly. The carriage holds the head assembly at rest during recording or reproduction and moves the head assembly at right angles to the direction of transportation of the magnetic recording medium to change the tracks to be recorded or to be reproduced. The centers of the head gaps of the magnetic heads fall in a straight line which is at right angles to the direction of transportation of the magnetic medium and the separations therebetween are determined by the conditions that almost all the tracks are tracked by the magnetic heads, practically without leaving any unrecorded tracks within the recording region of the magnetic recording medium, and that magnetic interference between the magnetic heads is negligible.
