A data storage tape cartridge includes a housing having a surface resistivity in a range of approximately 10ohms/square to approximately 10ohms/square, at least one tape reel rotatably disposed within the housing, and a length of magnetic storage tape wound around the at least one tape reel.

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.

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.

A lifter for supporting a fabric finer of a flexible magnetic recording disc, such as a floppy diskette, so that the disc is cleaned by rotation of the disc with respect to the liner. The lifter is in the shape of a parallelogram having interior angles of about 85.degree. and 95.degree.. The lifters are cut from a length of planar, polyester material with a single, straight cut, so that all of the material is used to make the lifters, thereby minimizing wastage of material during the production of lifters for floppy diskette cartridges.
