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.
Claims15
A hard disk drive that is coupled to a source of heat, comprising:
- a disk;
- a head coupled to said disk;
- a housing that encloses said disk and said head, said housing having an opening;
- a first desiccant coupled to said housing adjacent to said opening;
- and,
- a second desiccant that is coupled to said first desiccant and the source of heat.
A hard disk drive, comprising:
- a disk;
- a head coupled to said disk;
- a housing that encloses said disk and said head, said housing having an opening;
- a first desiccant coupled to said housing adjacent to said opening;
- and,
- regenerating means for regenerating said first desiccant.
A method to regenerate a first desiccant of a hard disk drive, comprising:
- applying heat to the first desiccant through a second desiccant to cause evaporation of fluid within the first desiccant, the fluid flows from the first desiccant into the second desiccant.
