Abstract
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.
