Abstract

In the process of assembling the parts of tape recording heads, fracturing of the ferrite material occurs due to its hardness and brittleness. This head makes use of a shield overlay for strengthening the ferrite material.

Copper Shield for Ferrite Heads

In the process of assembling the parts of tape recording heads, fracturing of the ferrite material occurs due to its hardness and brittleness. This head makes use of a shield overlay for strengthening the ferrite material.

The tape head is formed of the pole pieces 1 and 2 which define a transducing gap 3. Pieces 1 and 2 are made of the ferrite material. To overcome the fracturing of the ferrite material due to handling, a layer of copper is electroplated over the ferrite material previously metallized. To prevent the occurrence of a short, gap 3 is free of any conducting material and slit 4 is provided around the side of the head.
