PURPOSE:To make magnetic path substantially continuous and increase the magnetic flux at the operating gap portion by forming the magnetic head from a pair of core materials through coupling the end parts of the core materials by means of a ferromagnetic amorphous alloy layer at the back gap side. CONSTITUTION:The portions of a pair of head chips 3, 4 other than the end parts 3a, 4a on their back gap 5 side are masked with photo resist or insoluble paint. With the head chips 3, 4 as one electrode, electric plating is applied to the head chips and a ferromagnetic amorphous alloy lear 6 is depositied on the portion of the back gap part 5, whereby these are bonded and integrated. The solution comprising, e.g., iron sulfamate; 56 (g/l), L-ascorbic acid; 5 (g/l), urea; 120 (g/l), ammonium sulfamate; 49 (g/l), sodium hypophosphite; 10.6 (g/l), brightener; slight is used as the plating solution, and the pH of the solution is desirably about 1 to 2.2 and the current density about 5 to 20A/(dm)<2>. |
