| Abstract |
The current distribution around rectangular cathode used in permalloy plating for the production of magnetic recording head was predicted by use of boundary element method. Three dimensional grid generator was made for the calculation of complex domain. It can be also used for curved surface. Experimental data were compared with those calculated values and fairy good agreement was observed. The effect of cell geometry and auxiliary electrode on current distribution was simulated. For the plating on the circular wafer, modification of the shape of auxiliary electrode was proposed for maximization of cathode area when active area density of cathode is smaller than that of auxiliary electrode. |
