MAGNETIC HEAD WITH SATURABLE GAP AND MATRIX DEVICE COMPRISING A MULTIPLICITY OF SUCH HEADS |
摘要 |
A magnetic head employs a gap of magnetic material between two poles. The magnetic material of the gap has a saturation value less than the saturation value of the poles. When the gap material is not saturated, the magnetic field remains contained within this gap.
