Abstract

PURPOSE:To obtain a head with good solderability especially for a ''Sendust '', good fluidity, almost equal thermal expansion, good wear-proof performance and high accuracy, by using a glass including a specific rate of oxide of a specific metal for the bonding of magnetic head cores made of a metallic magnetic substance material. CONSTITUTION:A notch 2 and a pack 3 which control a track width 1 of a core using a metallic magnetic substance, especially a high magnetic flux density metallic magnetic substance such as ''Sendust '' are bonded through the use of a glass including 2-15wt% of one type or more out of Fe2O3, MnO2, ZnO, NiO and CuO. The said glass has excellent solderability to the metallic magnetic substance and good fluidity, then a mganetic head with high accuracy can be mass-produced with efficiency.
