GLASS-BONDED MAGNETIC HEAD AND METHOD OF MANUFACTURING SAME |
摘要 |
<p>A magnetic head (32) includes a magnet core (30) of ferrite and a layer of a bonding material (28) consisting of glass in the gap-forming area of the magnet core (38). In order to ensure that the ferrite is not attacked by the glass during the bonding process and that the temperature adjustment during the bonding process is not too critical, double layer diffusion barriers are provided between the layer of bonding material (28) and the core parts (10), (10'), respectively. Each barrier is formed by a layer of silicon nitride (26) on the side of the bonding layer (28) and a layer of silicon oxide (24) on the side of the core.</p> |
