Iron-oxidized hard disk drive enclosure cover |
| 摘要 |
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. |

1. A hard disk drive comprising:
a base; at least one disk medium rotatably mounted on a spindle; a head slider comprising a read/write head configured to read from and to write to said disk medium; a voice coil actuator configured to move said head slider to access portions of said disk medium; and a pre-oxidized cover coupled with said base to form an enclosure for said disk medium, said head slider, and said voice coil actuator, wherein a surface of said pre-oxidized cover is substantially free of un-oxidized metallic iron, and wherein said enclosure is substantially filled with a gas that is lighter than air. |
