Abstract:
A recording-reproducing magnetic head comprising a magnetoresistance effect reproducing head and an inductive recording head;said magnetoresistance effect reproducing head including a magnetoresistance effect element; said inductive recording head including a lower magnetic core, an upper magnetic core, coils sandwiched between said lower and upper magnetic cores at mid-parts thereof, and a recording magnetic gap layer sandwiched between said lower and upper magnetic cores at leading end parts thereof; said leading end parts of said lower and upper magnetic cores having a protruding part protruding to said recording magnetic gap layer; wherein said leading end part of said lower magnetic core further has a second protruding part protruding toward said magnetoresistance effect element; said upper magnetic core having a continuous magnetic body which extends from said protruding part to said mid-part; and a center line of said protruding part of said lower magnetic core, which extends in a track length direction on a surface opposite a medium, intersecting said protruding part of said upper magnetic core.
