Abstract
A method of adjusting a humidity within an interior of an enclosure of a data storage device comprises detecting a trigger condition, and in response to detecting the trigger condition, heating a water-releasing substance situated within the interior of the enclosure of the data storage device to release water, thereby increasing the humidity within the interior of the enclosure of the data storage device. A data storage device comprises a water-releasing substance; a heater configured to heat the water-releasing substance; and a controller configured to control the heater to cause the water-releasing substance to release water.
Claims29
A method of adjusting a humidity within an interior of an enclosure of a data storage device, the method comprising:
- detecting a trigger condition;
- and
- in response to detecting the trigger condition, heating a water-releasing substance situated within the interior of the enclosure of the data storage device to release water, thereby increasing the humidity within the interior of the enclosure of the data storage device, wherein the water-releasing substance comprises sodium percarbonate (Na2CO3· 1.5H2O2).
A method of adjusting a humidity within an interior of an enclosure of a data storage device, the method comprising:
- detecting a trigger condition;
- and
- in response to detecting the trigger condition, heating a water-releasing substance situated within the interior of the enclosure of the data storage device to release water, thereby increasing the humidity within the interior of the enclosure of the data storage device,
- wherein:
- the water-releasing substance is situated in a core area of a voice coil winding of the data storage device;
- and
- heating the water-releasing substance situated within the interior of the enclosure of the data storage device comprises causing current to flow through the voice coil winding.
A data storage device, comprising:
- a water-releasing substance;
- a heater configured to heat the water-releasing substance;
- and
- a controller configured to, in response to an occurrence of a trigger condition, control the heater to increase a temperature of the water-releasing substance to cause the water-releasing substance to release water, wherein the water-releasing substance comprises sodium percarbonate (Na2CO3· 1.5H2O2).
A data storage device, comprising:
- a water-releasing substance;
- a heater configured to heat the water-releasing substance;
- and
- a controller configured to, in response to an occurrence of a trigger condition, control the heater to increase a temperature of the water-releasing substance to cause the water-releasing substance to release water,
- wherein:
- the water-releasing substance is situated in a core area of a voice coil winding of the data storage device;
- and
- the heater comprises the voice coil winding.
