PURPOSE:To mass-produce magnetic recording and reproducing elements easily without dispersion in characteristics, by forming a winding and a core closely. CONSTITUTION:A pattern of the 1st layer 10a of a winding 10 is formed on a base 8 of a nonmagnetic substance with a conductive material. This pattern is formed with the vacuum-deposition method or the sputtering method, and then with the photoetching means. After attaching an insulating film on the pattern, a core 9 with the required pattern is formed, then the insulating film is attached again and the pattern 10b of a conductive material, i.e. the pattern of the 2nd layer 10b of the winding 10 is adhered. Finally, the core is cut off at the line C-C, the cut-surface is polished to form a sliding plane for the completion of a magnetic recording and reproducing element. |
