    摘要: In one illustrative example, a method for use in making a magnetic write head includes the steps of forming a first pole piece layer of a first pole piece; forming a patterned resist over the first pole piece layer; electroplating a pedestal over the first pole piece layer within a channel of the patterned resist; electroplating a metal gap layer over the pedestal within the channel of the patterned resist; forming a resist channel shrinking film over the patterned resist; baking the resist channel shrinking film over the patterned to thereby reduce a width of the channel; removing the resist channel shrinking film; electroplating a second pole piece within the reduced-width channel of the patterned resist; removing the patterned resist; and milling the pedestal, using the second pole piece as a mask, to form a central notched pedestal having side walls with angled slopes.

    摘要: A pedestal is formed over a first pole piece layer and insulator materials are formed to surround it. A gap layer made of a non-magnetic insulator or metal is then formed over the pedestal and the insulator, followed by the optional formation of a seed layer. A second pole piece is formed over the gap layer with or without the seed layer by forming a patterned resist using E-beam lithography and electroplating second pole piece materials within the patterned resist. After milling to remove side portions of the gap layer and the optional seed layer, a chemical etch is performed to remove a top portion of the insulator materials. The pedestal is then notched and trimmed by ion milling using the second pole piece as a mask to form a central notched structure. Since the second pole piece is precisely centered over the pedestal prior to notching, the pedestal is notched symmetrically to form a notched structure having side walls with angled slopes.

    摘要: A method for manufacturing thin-film magnetic head sliders is disclosed. Initially, an elastic layer, which may be made of poly-dimethyl siloxane (PDMS), is spun on a wafer and is thermally cured. Then, a resist layer is spun on the elastic layer. Both the resist layer and the elastic layer are subsequently peeled off together from the wafer. Next, the peeled resist layer/elastic layer is applied onto a group of magnetic heads with the resist layer in direct contact with the magnetic heads. Finally, the elastic layer is peeled off from the resist layer such that the resist layer remains attaching to the magnetic heads.

    摘要: Methods of forming a component of a thin film magnetic head and improving the plating of a component of a thin film magnetic head are provided. The methods include the use of a high activation energy chemically amplified photoresist (CARS) that is contacted with a low pH high saturation magnetic moment plating solution to form a magnetic head component that is essentially free of plating defects. The methods find utility in hard disk drive applications, such as in the manufacture of magnetic poles for the write head of a hard disk drive.

    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.
