Abstract
A disk drive having a moisture-absorbent element of compactly folded cloth formed by weaving stainless steel fibers for suppressing the humidity rise in the case accompanying a temperature fall. A disk is housed in an upward open box-shaped case. A magnetic head for writing and reading information on the disk is supported by a head drive. On the top of the case, a cover is fixed by a plurality of screws to nearly seal the interior of the drive. Between the case and the cover is disposed a moisture-absorbent element of compactly folded cloth formed by weaving stainless steel fibers. Held between the bottom of the case and the lower surface of the cover, the moisture-absorbent element is fixed in the drive.
