MAGNETORESISTIVE ELEMENT, MAGNETORESISTIVE HEAD, MAGNETORESISTIVE CONVERSION SYSTEM, AND MAGNETIC RECORDING SYSTEM

Title:

MAGNETORESISTIVE ELEMENT, MAGNETORESISTIVE HEAD, MAGNETORESISTIVE CONVERSION SYSTEM, AND MAGNETIC RECORDING SYSTEM

Document Type and Number:

Japanese Patent JP2005184014

Kind Code:

A

Abstract:

To provide a magnetoresistive element, a magnetoresistive head, a magnetoresistive conversion system, and a magnetic recording system, wherein a sense current is prevented from flowing to a vertical bias layer, noise is little in a reproduction waveform, and an S/N ratio and a bit error rate are execellent.

In the direction of a magnetic field applied by a vertical bias layer 2b, the length of a free layer 3b is set longer than that of a fixed layer 5, and the free layer 3b is disposed in the vicinity of the vertical bias layer 2b while a distance between the fixed layer 5 and the vertical bias layer 2b is maintained.
