Abstract: A method and system for programming a magnetic memory is disclosed. The method and system further include turning on a word line current and turning on a bit line current. The word line current is for generating at least one hard axis field. The bit line current is for generating at least one easy axis field. In one aspect, the method and system further include turning off the word line current and the bit line current such that a state of the at least one magnetic memory cell is repeatably obtained. In another aspect, the word line current is turned off after the bit line current is turned off.

Abstract: A magnetic recording head is fabricated with a pole tip shielded laterally on its sides by a pair of symmetrically disposed side shields formed of porous heterogeneous material that contains non-magnetic inclusions. The non-magnetic inclusions, when properly incorporated within the magnetic matrix of the shields, promote the formation of flux loops within the shields that have portions that are parallel to the ABS and do not display locally disorganized and dynamic regions of flux during the creation of magnetic transitions within the recording medium by the magnetic pole. These flux loop portions, combine with the magnetic flux emerging from the main pole to create a net writing field that significantly reduces adjacent track erasures (ATE) and wide area erasures (WATE).
