PURPOSE:To improve yield and operativity and to decrease the number of parts, by notching the outside of a core in front of and behind a recording and reproducing gap for the formation of the gap, and further notching the inside of the core in front of and behind an erasing gap for the formation of the erasing gap. CONSTITUTION:A core 11 nearly in an L shape has its tip part 11a notched externally and the notched parts are charged with glass materials 12 and 13; and a core 14 nearly in the same shape with the core 11 has its tip part 14a notched internally and the notch part is charged with glass 15. An intermediate core 16 in an I shape consist of a couple of cores 18 and 19 bonded together with glass 17 at a specific interval. The core 18 has the upper end notched externally and the core 19 has the upper end notched internally; and those notched parts are charged with glass materials 18a and 18b, and 19a. Then, the core 11 is connected to the core 18 of the intermediate core 16 by glass deposition while the recording and reproducing gap 20 is formed, and the core 14 is jointed to the core 19 by glass deposition while erasing gaps 21 and 22 are formed. Consequently, the magnetic head consisting of less parts is realized. |
