Abstract

PURPOSE: To improve detection sensitivity and to facilitate manufacture by specifying bias magnetic filed HL applied in a signal magnetic field direction to signal magnetic field HS applied to a magnetic resistance effect (MR) element.
CONSTITUTION: To MR element 1, conductor layer 2 through which electric current is flowed is connected and direct current (i) is flowed in direction (x) to detect HS from recording track 4 on recording medium 3. In this case, the relation among HS, anisotropic magnetic field HK of element 1, diamagnetic field coefficient HD in direction HS of element 1, and HB applied in direction HS to element 1 is set as shown by the equations. Thus, width (w) and thickness (t) of element 1 are set within a range of easy work and this magnetic head is enabled to detect magnetic information with good sensitivity.
