Abstract
A magnetic head for recording having horizontal pole pieces. The magnetic head includes a lower subassembly mounted on a substrate including a lower magnetic layer, two magnetic pillars and a conductor winding. An insulating ridge having inclined sides and a flat apex is mounted on the lower subassembly. Two flux concentrators are mounted on the sloping sides of the insulating ridge and end in a face which is flush with the apex of the ridge. The pole pieces are formed as straight bars and mounted on top of the inner ends of the flux concentrators.
