  • METHOD AND SYSTEM FOR MONITORING GAS IN SEALED HARD DISK DRIVES WITH FEEDBACK
    Publication number: 20090296271
    Abstract: A system and method for monitoring the helium content of a disk cavity of a hard disk drive is disclosed. In one embodiment of the present invention, an oxygen sensor is placed in the disk cavity to monitor the level of oxygen in the cavity. With the measurement of oxygen in the disk cavity, the level of helium in the cavity is inferred. In one embodiment, if the amount of helium inferred from the oxygen level fell below 90% - 95% of the gaseous content of the disk cavity, a user is automatically notified in order to maintain the hard disk drive in a timely manner.
