Thin-film vertical magnetization transducer head

A vertical magnetization transducer head, comprising:

• a support having an air gap;
• first coil segments arranged on said support on a first side of said air gap;
• a first nonmagnetic layer arranged on said support and on midportions of said first coil segments;
• a second nonmagnetic layer arranged on a portion of said first nonmagnetic layer located on a second, opposite side of said air gap;
• a first magnetic layer arranged on a portion of said first nonmagnetic layer on said first side of said air gap;
• a second magnetic layer having a first portion arranged on said first magnetic layer and a second portion arranged on said second nonmagnetic layer, said first and second portions defining therebetween a magnetic air gap extending to the air gap of said support;
• a third magnetic layer arranged on said first portion of the second magnetic layer;
• a third nonmagnetic layer arranged on said third magnetic layer, which third nonmagnetic layer covers side portions of the first, second and third magnetic layers;
• and
• second coil segments arranged on said third nonmagnetic layer, opposite ends of the second coil segments extending into contact with opposite ends of said first coil segments to form a coil,
• said second portion of said second magnetic layer forming a main magnetic pole member having a first thickness and a first width, and said first magnetic layer, said first portion of said second magnetic layer and said third magnetic layer defining an auxiliary magnetic pole member having a second thickness greater than said first thickness and a second width greater than said first width.
