Abstract
A magnetic head supporting structure comprises a metal purified by vacuum arc remelting, vacuum induction melting, electroslag remelting, or electroslag remelting under vacuum, in at least one of the regions that undergo plastic deformation during disk drive manufacture, to reduce small hard inclusions that might be released into the disk drive interior environment.
