Patent number: 9293161Abstract: An iron-oxidized hard disk drive (HDD) cover has an inner surface that is substantially free of un-oxidized or pure metallic iron, fabricated by baking a stainless steel cover and thereby oxidizing the cover surface of iron. Because the cover is iron-oxidized, a costly nickel-plating process may be foregone while a “Fe smear” problem may be significantly reduced. Such an iron-oxidized cover is especially beneficial for, though not limited to, use as an inner cover in a sealed HDD.Type: GrantFiled: November 4, 2015Date of Patent: March 22, 2016Assignee: HGST Netherlands B.V.Inventors: Yuki Taniguchi, Kazushi Tsuwako, Koichi Suzuki, Masahiko Tamura
