发明名称 High efficiency magnetic erase head
摘要 In a magnetic transducer of the type including a pair of opposed, generally C-shaped pole pieces positioned in facing relationship with a gap between first ends of the pole pieces, each pole piece being formed from a ferrite material and having a coil would therearound, and at least one length of conductive gap material positioned within the gap so as to shunt the magnetic lines of flux flowing through the pole pieces into a magnetic recording medium which engages the pole pieces in the area of the gap, there is disclosed an improved erase head wherein an elongate bar made from a conductive material is positioned between the pole pieces, in the cavity therebetween, parallel thereto and to the gap and spaced from the gap.
