Abstract

PURPOSE: To obtain a low-cost magnetic tape head which excels in the hardwearing properties by providing the aluminum anode oxide film impregnated with the Teflon onto the tape sliding surface of the head.
CONSTITUTION: Coating film 7 is provided to the magnetic tape head which is formed with magnetic core 1 wound round by coils 4 and 5 and opposed via gap spacer 2 and then distributing the core into case 6 via filler 3. In other words, the aluminum is evaporated over the entire area of surface 10 where the head rubs the tape and through the micron order, and then formed into porous oxide film 8 through the anode oxide film process. Then the Teflon is applied on film 8 to be impregnated into the minute hole of film 8. At the same time, the smooth Teflon surface layer is formed to be used as coating film 7.
