Abstract:
In hard disk drive (HDD), the distance between magnetic head and media during read write process is less than 10 nm. During HDD production, nm-sized contaminants of metal oxides are often seen attached strongly on the head surface, thus significantly reducing drive reliability. This paper will describe a series of electrochemical measurements to determine the factors that would diminish attracting force between contaminants and magnetic head surface. One type of magnetic alloy, namely NixFey, was used as a representative for magnetic head component. We saw a correlation between the Fe composition in NixFey alloy and surface charge. In addition, we determined that the surface charge of magnetic head could be altered by changing electrolyte conductance, addition of anionic surfactant and adjusting the pH in the solution. We also found that once the surface charge is dropped to a certain value, a significant reduction of contaminants attached on the magnetic head was seen. The result presented here could be useful for designing a new process for eliminating nm-sized contaminants in electronic production industry
