Abstract
Described are methods of forming write poles using physical vapor deposition or chemical vapor deposition of FeCoX magnetic material alloys, where the X element is selected to produce properties such as oxidation resistance, corrosion resistance, and sufficiently high magnetic moment. Once an initial portion of the write pole is formed by depositing the FeCoX alloy, the remainder of the write pole may be formed by electroplating an FeCo-based alloy using the deposited FeCoX as an electroplating template, or by deposition of additional FeCoX material to form the bulk of the write pole.
Claims20
A method for making a magnetic writer having a write pole, the method comprising:
- depositing an FeCoIr alloy using physical vapor deposition techniques or chemical vapor deposition techniques to thereby form an initial portion of the write pole;
- electroplating an FeCo-based alloy using the initial portion of the write pole as a seed for the electroplating to thereby form a remaining portion of the write pole;
- and
- incorporating the write pole into the magnetic writer.
A method for making a magnetic writer having a write pole, the method comprising:
- depositing an FeCoX alloy to thereby form an initial portion of the write pole, wherein X is selected to increase resistance to oxidation relative to FeCo while maintaining a magnetic moment of 2 T or greater;
- forming a remaining portion of the write pole on the initial portion of the write pole;
- and
- incorporating the write pole into the magnetic writer.
