Magnetic head closure having ferrite substrate and closure and conductive thin film coil deposited in recess of substantially same shape in ferrite substrate

A magnetic head having a transducing surface, comprising:

• a ferrite substrate having a first recess formed in a predetermined surface thereof;
• a ferrite closure fitted to said predetermined surface of said ferrite substrate;
• a conductive thin film coil deposited in said first recess in a substantially same shape as said first recess;
• an insulative layer deposited on said ferrite substrate and covering said conductive thin film coil, at least a portion of said insulative layer adjacent said transducing surface forming a transducing gap;
• and
• a second recess formed in a surface of said ferrite closure so as to enclose a portion of said conductive thin film coil adjacent said transducing gap, wherein said second recess has first and second inclined surfaces, an edge of said first inclined surface nearest said transducing gap being disposed in such a position as to define a depth of said transducing gap, and an edge of said second inclined surface being disposed away from said transducing surface a predetermined distance from said portion of said conductive thin film adjacent said transducing gap.
