Abstract :
We have investigated a thin film head for VCR application whose structure has a long depth and a gap surface that is perpendicular to the substrate. We made a test device that has a CoZr amorphous thin film core. The conductor is a helicoid that is wound three-dimensionally around the core and is fabricated by thin film processes. The thin film head obtained larger normalized output voltage by track width and inductance than a MIG head between 1 to 10 MHz
