Abstract
A disk drive that regenerates a desiccant within the drive. The drive includes a housing that encloses a head and a disk. A first desiccant is located adjacent to a hole of the housing. A second desiccant is coupled to the first desiccant. The second desiccant is also coupled to a source of heat. Heat is transferred through the second desiccant to the first desiccant. The heat evaporates fluid within the first desiccant. The evaporated fluid flows into and through the second desiccant. The evaporation of fluid regenerates the first desiccant so that is can continuously absorb humidity within the drive.
