Non-magnetic part in magnetic head assembly

A component of a magnetic assembly, said assembly comprising:

• a read/write core comprised of a Ni-Zn ferrite;
• a first reinforcing member abutted to an edge of said read/write core, said reinforcing member being comprised of 30 to 50 volume % TiO.sub.2 and 70 to 50 volume % of a mixture of Ba.sub.2 Ti.sub.9 O.sub.20 and BaAl.sub.2 Ti.sub.5 O.sub.14 wherein the volume ratio of Ba.sub.2 Ti.sub.9 O.sub.20 to the total volume of Ba.sub.2 Ti.sub.9 O.sub.20 and BaAl.sub.2 Ti.sub.5 O.sub.14 is in the range of from 0.05 to 0.5;
• a pair of erase cores, each of said erase cores being bonded on opposite sides of said read/write core, said erase cores being comprised of Ni-Zn ferrite;
• and
• second and third reinforcing members, of said second and third reinforcing members being abutted to one edge of one of said erase cores respectively, said second and third reinforcing members being comprised of 30 to 50 volume % TiO.sub.2 and 70 to 50 volume % of a mixture of Ba.sub.2 Ti.sub.9 O.sub.20 and BaAl.sub.2 Ti.sub.5 O.sub.14 wherein the volume ratio of Ba.sub.2 Ti.sub.9 O.sub.20 to the total volume of Ba.sub.2 Ti.sub.9 O.sub.20 and BaAl.sub.2 Ti.sub.5 O.sub.14 is in the range of from 0.05 to 0.5;
• said first, second and third reinforcing members being comprised of a three-component mixture of TiO.sub.2, BaAl.sub.2 Ti.sub.5 O.sub.14 and Ba.sub.2 Ti.sub.9 O.sub.20.
