20100107402 | Methods Of Making Magnetic Write Heads With Use Of A Resist Channel Shrinking Solution Having Corrosion Inhibitors - One preferred method for use in making a device structure with use of the resist channel shrinking solution includes the steps of forming a first pedestal portion within a channel of a patterned resist; applying a resist channel shrinking solution comprising a resist channel shrinking film and corrosion inhibitors within the channel of the patterned resist; baking the resist channel shrinking solution over the patterned resist to thereby reduce a width of the channel of the patterned resist; removing the resist channel shrinking solution; and forming a second pedestal portion within the reduced-width channel of the patterned resist. Advantageously, the oxide layer and the corrosion inhibitors of the resist channel shrinking solution reduce corrosion in the pedestal during the act of baking the resist channel shrinking solution. | 05-06-2010 |
20090034135 | Differential magnetoresistive magnetic head - Embodiments of the present invention help to provide a single element type differential magnetoresistive magnetic head capable of achieving high resolution and high manufacturing stability. According to one embodiment, a magnetoresistive layered film is formed by stacking an underlayer film, an antiferromagnetic film, a ferromagnetic pinned layer, a non-magnetic intermediate layer, a soft magnetic free layer, a long distance antiparallel coupling layered film, and a differential soft magnetic free layer. The long distance antiparallel coupling layered film exchange-couples the soft magnetic free layer and the differential soft magnetic free layer in an antiparallel state with a distance of about 3 nanometers through 20 nanometers. By manufacturing the single element type differential magnetoresistive magnetic head using the magnetoresistive layered film, it becomes possible to achieve the high resolution and the high manufacturing stability without spoiling the GMR effect. | 02-05-2009 |
