Abstract
A system and method for providing a head for reading data is disclosed. The method and system include providing a magnetoresistive element and providing a flux guide having a high resistivity. The magnetoresistive element has an end. The flux guide also has an end. The end of the flux guide is adjacent to the end of the magnetoresistive element.
Claims6
A method for providing a magnetic head for reading data comprising the steps of:
- (a) providing a magnetically soft film made of ferrite;
- (b) removing by use of a mask and by etching a portion of the magnetically soft film to form a flux guide;
- and
- (c) providing a magnetoresistive film adjacent to said flux guide, and by using said mask while still in place for removing and etching said portion of the magnetically soft film, forming a magnetoresistive element having an end adjacent to the flux guide.
