A method of making a rotating removable data storage device hub, such as a hub for a micro-floppy magnetic data storage disc, that has a core of plain carbon steel and a primary coating. The hub also includes a vapor corrosion inhibiting layer on the primary coating. The plain carbon steel can have about 0.5% or less carbon. The primary coating can be tin, nickel, zinc, chrome, paints, epoxies, epoxy-urethanes, phenolic resins, and combinations thereof. The vapor corrosion inhibiting layer may include an amine to reduce the rate of oxidation of the plain carbon steel core.

Plain carbon steel hub for data storage device

A plain carbon steel shutter for a removable data storage device includes a primary coating thereon to improve its appearance, wear, durability and resistance to corrosion. In addition to the primary coating, the shutter also includes a vapor corrosion inhibitor to reduce corrosion caused by ambient moisture in the atmosphere. To increase stiffniess, the fillet radius of the bends in the shutter are increased.
