Abstract: High-performance laminated sputtered Sendust (LSS) video heads with high abrasion resistance have been realized by using a newly developed CaO-TiO/sub 2/-NiO ceramic substrate. For acceptable head abrasion for practical use of 15 mu m, head life is more than 1000 h at more than 20 m/s relative tape-head speed. Low magnetostriction Sendust films provide high reproduce voltage for the head. The LSS head, with CaO-TiO/sub 2/-NiO substrate, has sufficient performance for use as high-definition television (HDTV) video tape recorder (VTR) heads. >
