Abstract
A moisture absorbing agent is used in a disk apparatus. The difference in the moisture absorption amount in the hygroscopic isothermal line between the moisture absorbing agent at a relative humidity of 80% and the moisture absorbing agent at a relative humidity of 95% is not less than 30% in the moisture absorbing stage and is not less than 20% in the moisture releasing stage relative to the dry weight of the moisture absorbing agent.
Claims8
A disk apparatus, comprising:
- a base body;
- a disk medium, a driving mechanism for supporting and rotating said disk medium, a head equipped with an element for reading information recorded on the disk medium, a carriage assembly supporting the head in a manner to be movable relative to the disk medium, and a condensation preventing member, which are placed on the base body;
- and
- a lid body covering the base body;
- wherein said condensation preventing member contains a moisture absorbing agent exhibiting a different moisture absorption amount depending on the humidity, the difference in said moisture absorption amount in its hygroscopic isothermal line between the moisture absorbing agent at a relative humidity of 80% and the moisture absorbing agent at a relative humidity of 95% being not less than 30% in the moisture absorbing stage and not less than 20% in the moisture releasing stage based on the dry weight of the moisture absorbing agent.
