Abstract
PURPOSE: To increase output by superposing a magnetic film, which is used as a magnetic path, onto a film for gap in the film thickness direction to form a gap and determining a track width in respect to the magnetic flux convergence-type MR head (MR; magnetoresistance effect element).
CONSTITUTION: Thin piece 6 for gap consisting of Au or SiO2 is formed at the gap joint part of Permalloy material 5 which lacks in the magnetic path partially, and next, Permalloy material 7 is formed on this piece 6 to provide spaces 9 and 10 between element parts, thereby obtaining a magnetic flux convergence-type Mr head of gap length 3 having MR element part 1. The head above is safe from defacement of the MR element and thermal noise generation and has a track width and a gap length which can be arbitrarily formed easily and is small-size and has a reproducing output several to several-ten times as large as that of the conventional head.
