Dual Gap Ferrite Head

The above figures depict a magnetic transducer which allows easy alignment between the read/write gap 10 and the erase gap 12.

The magnetic transducer includes a ferrite center section 14 and two end sections 16 and 18, respectively. The two end sections are glassed to the center section by a conventional technique to define the write/read gap and the erase gap. In order to separate the write/read gap from the erase gap, a decoupling slot is positioned within center section 14. Notches 20 and 22 are positioned on either side of center section 14 and function to determine the throat height of the head.

In order to achieve read/write narrow and erase wide, notch 24 is fabricated in the top section of the head.

In order to achieve accurate alignment between the read/write gap and the erase gap, the core is slightly tilted or rotated about the midpoint between the two gaps.
