MR Head Response From Arrays Of Lithographically Patterned Perpendicular Nickel Columns


In an effort to explore the feasibility of a patterned perpendicular magnetic storage medium, we have lithographically prepared arrays of nickel columns embedded in SiO_2. The arrays have been planarized using a chemical mechanical polish. By raster-scanning a magnetoresistive (MR) head in contact with the medium, we have obtained magnetic images of the arrays, demonstrating the ability to "read" the magnetization state of the Ni columns.
