MAGNETIC SENSOR, MAGNETIC HEAD, AND MAGNETIC RECORDER

摘要

PROBLEM TO BE SOLVED: To provide a magnetic sensor, a magnetic head, and a magnetic recorder using an antiferromagnetic domain control film without making it difficult to choose materials or to control a manufacturing process. SOLUTION: Either a part or all of a spin valve film is made to extend along each side of a magnetic sensing part, a bent part is provided to the extended part of the spin valve film, and antiferromagnetic layers 3 and 4 are arranged on the extended part extended from the bent parts.
