MAGNETIC RELUCTANCE HEAD

摘要

PROBLEM TO BE SOLVED: To obtain a magnetoresistive head protected against electrostatic discharge without requiring any additional production step. SOLUTION: The MR sensor comprises an SFB magnetic reading sensor 69 sandwiched by two magnetic materials 81, 83 having high resistivity. The MR sensor is disposed between two MR shields each connected through a resistor 89 with an MR sensor ground signal lead 88. The resistor is made of a magnetic material having high resistivity deposited in same production step as the MR sensor.
