Magnetoresistance effect element

摘要

The magnetoresistance effect element can be manufactured by a conventional process and is capable of restricting influences of noises or leaked magnetic signals so that magnetic recording density can be highly improved. The magnetoresistance effect element comprises: a magnetoresistance film including a free layer; and shielding sections being respectively provided on the both sides of the free layer in a direction of track width, the shielding sections being soft magnetic films.
