Devices and methods for metal organic framework (MOF) based oxygen replenishment in data storage devices

A data storage device, comprising:

• a sealed enclosure;
• a spindle motor situated within an interior of the sealed enclosure;
• a metal organic framework (MOF) container situated within the interior of the sealed enclosure, wherein the MOF container contains a MOF configured to store captive molecular units and to release the captive molecular units in gaseous form into the interior of the sealed enclosure;
• a heater situated within the interior of the sealed enclosure, wherein the heater is configured to heat the MOF;
• and
• a controller coupled to the heater, wherein the controller is configured to set or adjust a heat output of the heater based at least in part on an indication of an amount or concentration of a gas within the interior of the sealed enclosure, the indication of the amount or concentration of the gas within the interior of the sealed enclosure being based at least in part on one or more of:
• a current of the spindle motor, a power consumption of the spindle motor, a proxy for the current of the spindle motor, or a proxy for the power consumption of the spindle motor.
