Abstract
A magnetic disk device according to an embodiment includes a housing in which a base, an inner cover provided with a first through-hole, and an outer cover are combined in this order and hermetically sealed, a magnetic disk that is stored in the housing, a first desiccant unit that is provided at the inner cover to face the base at a position away from the base, and a second desiccant unit that is provided at the outer cover and inserted into an internal space of the housing through the first through-hole provided in the inner cover to face the base at a position away from the base.

A magnetic disk device further comprising:
- a housing in which a base, an inner cover provided with a first through-hole, and an outer cover are combined in this order and hermetically sealed;
- a magnetic disk that is stored in the housing;
- a first desiccant unit that is provided at the inner cover to face the base at a position away from the base;
- a second desiccant unit that is provided at the outer cover and inserted into an internal space of the housing through the first through-hole provided in the inner cover to face the base at a position away from the base;
- and
- a gasket interposed around the second desiccant unit, the gasket sealing a gap in the first through-hole generated between the second desiccant unit and the inner cover.
A magnetic disk device comprising:
- a housing in which a base, an inner cover provided with a first through-hole, and an outer cover are combined in this order and hermetically sealed;
- a magnetic disk that is stored in the housing;
- a first desiccant unit that is provided at the inner cover to face the base at a position away from the base;
- and
- a second desiccant unit that is provided at the outer cover and inserted into an internal space of the housing through the first through-hole provided in the inner cover to face the base at a position away from the base, wherein
- the first desiccant unit includes a first case filled with a first desiccant,
- the second desiccant unit includes a second case filled with a second desiccant, and
- the first and second desiccants are each an irreversible adsorbent having hygroscopicity even in a lower-humidity environment than a humidity environment in which a reversible adsorbent capable of recovering hygroscopicity by drying is capable of exhibiting hygroscopicity.
