ABSTRACT:
A shutter for use on a housing of a disk-based memory medium is formed of aluminum alloy sheet stock that is bent to form a spine with integral side legs or aprons. A surface-hardening coating is formed on both legs near the spine to increase the wear resistance of the shutter in the area where the shutter engages a shutter-opening mechanism that tends to introduce plastic deformation and metal debris after repeated contacts with the shutter-opening mechanism. The method for fabrication of the shutter includes stamping a slot in the sheet stock at a location which will form an edge of the shutter where plastic deformation occurs. A surface-hardening coating is formed on all exposed areas of the shutter, including the edge of the stamped slot. The shutter is trimmed and punched to its final size, and the shutter is bent to form a spine and a pair of legs, with the edges of the slots forming a wear-resistant edge on each leg near the spine.
