Magnetic sensor, magnetic head and magnetic recording apparatus |
摘要 |
A magnetic sensor having such a structure that a hard layer for controlling the magnetic domain formed of a conductive hard magnetic material, and a magnetic sensor layer, are at least partially in direct contact with each other, and current flows in the direction wherein at least a main component of current is perpendicular to the surface of the magnetic sensor layer. The current flowing in the magnetic sensor layer and the hard layer is controlled by changing the resistivity of the hard layer. The magnetic sensor is used as a magnetic read head in a magnetic recording apparatus such as magnetic disk apparatus.
