摘要： A magnetic recording medium with domain wall pinning sites including a substrate, a soft magnetic underlayer, and a magnetic recording layer overlying the soft magnetic underlayer. In one embodiment the magnetic recording layer has at least two grooves providing a track having first and second sidewalls formed by the grooves. The sidewalls provide a plurality of pinning sites formed between the sidewalls for pinning magnetic domain walls in the track. At least one of the pinning sites includes a first indentation in the first sidewall and a paired second indentation in the second sidewall. In one embodiment data can be stored within the magnetic recording layer by positioning a write head adjacent the track and inducing at least two magnetic domains defining a domain wall. The domain wall migrates to one of the pinning sites in the track.

摘要： A method is disclosed for independently controlling track width and bevel angle of a write pole tip of a magnetic recording head. The method includes establishing the track width in the pole tip layer material utilizing E-beam lithography. A portion of this pole tip material having the established track width is protected by providing a temporary masking material to make a protected portion. At least one unprotected portion is left exposed to be shaped. This unprotected portion is then beveled to produce at least one beveled portion. The protected portion produces an upper pole tip portion which together with the beveled portion produce an improved pole tip. Also disclosed is a magnetic head having the improved pole tip, and a disk drive having a magnetic head having the improved pole tip.

摘要： A method and apparatus for integrating a stair notch and a gap bump at a pole tip in a write head is disclosed. A protective plated layer is formed over the bump to prevent the bump form being damaged during formation of the notch at the pole tip. The flux from the second pole outside of the track will be effectively channeled to the first pole piece under the alumina bump.

摘要： A method and system for cleaning the silicon microlenses in an electron-beam microcolumn in situ. The microlenses individually are heated by passing a current through each microlens. The current is utilized to heat the microlens to at least two hundred degrees Centigrade to prevent contamination and occasionally to a temperature on the order of six to seven hundred degrees Centigrade to remove any builtup or potential contamination.

摘要： 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.
