Method of making a plain carbon steel hub for data storage device

A method of manufacturing a hub for a micro-floppy magnetic data storage disc comprising:

• a) forming a core consisting essentially of plain carbon steel, wherein the plain carbon steel comprises about 0.5% or less carbon;
• b) providing a primary coating on the core;
• and
• c) providing a vapor corrosion inhibiting layer on the primary coating.

A method of manufacturing a rotating removable data storage device comprising:

• a) forming a core of a hub, the core consisting essentially of plain carbon steel, wherein the plain carbon steel comprises about 0.5% or less carbon;
• b) providing a primary coating on the core;
• c) providing a vapor corrosion inhibiting layer on the primary coating;
• and
• d) attaching the hub to an annular ring of magnetic recording media.

• a) forming a core consisting essentially of plain carbon steel, wherein the plain carbon steel comprises about 0.5% or less carbon;
• b) providing a primary coating on the core;
• c) exposing the core to a source of a vapor corrosion inhibiting material to form a vapor corrosion inhibiting layer on the primary coating on the core;
• and
• d) removing the core from exposure to the source after formation of the vapor corrosion inhibiting layer.
