The magnetic properties of alumite film in which Co-Fe alloy electrodeposited are investigated with regard to the alloy composition and the geometric structure of the magnetic films. The Co-Fe particles electrodeposited in the alumite film are single phase alloy particles. The Co-Fe alloy electrodeposited films with small pore diameter (150 å) have a large maximum magnetic energy product (BHmax) of about 1.44 MGOe due to the high coercive force, high saturation magnetization and good squareness of the M-H curve. Therefore the Co-Fe alloy electrodeposited film has good possibility for perpendicular magnetic recording media of magnetic rotary encoders.
