Shutter for disk-based memory medium housing and method of fabrication

A method for fabricating a shutter from sheet rock metal of selected thickness for use on a housing of a disk-based memory medium, the method comprising the steps of:

• forming a slot with an edge at a selected location on the sheet rock;
• forming a surface-hardening coating on all exposed surfaces of the sheet rock including the thickness of the edge of the slot;
• trimming and punching the sheet stock to form the shutter with the edge of the slot disposed to form a portion of a spaced end of a leg integral with a spine;
• and
• bending the shutter to form the spine having spaced ends and a pair of integral legs along spaced edges of the spine and having spaced ends substantially aligned with the spaced ends of the spine, with the edge of the slot at the selected location disposed to form a portion of a spaced end of an integral leg in a region thereof near an end of the spine and having the surface-hardening coating thereon and being substantially aligned with an end of the spine.

A method for fabricating a shutter for a housing of a disk-based memory medium, the method comprising the steps of:

• forming a shutter of aluminum alloy of selected thickness having a spine and integral legs along edges of the spine between spaced ends thereof, and including an end of the leg of said selected thickness;
• forming a surface-hardening coating on the shutter, including on a portion of said end of selected thickness;
• and
• installing the shutter on a housing for sliding movement thereon in response to application of force to the shutter at said end of selected thickness.
