MAGNETORESISTIVE MAGNETIC HEAD, AND ELECTROMAGNETIC TRANSDUCTION CHARACTERISTIC MEASUREMENT METHOD AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a shield form and a measuring method capable of increasing measuring accuracy. SOLUTION: The shapes of shields 1 and 2 are designed such that the direction of a magnetic field effectively applied on a magneto-resistance effect element 3 is perpendicular to a medium opposite surface 4. Alternatively, a problem is solved by carrying out measuring with the angleθof an applied magnetic field inclined such that the direction of a magnetic field effectively applied on the magneto-resistance effect element 3 is perpendicular to the medium opposite surface 4.
