  • Patent number: 9685201
    Abstract: A system according to one embodiment includes a magnetic structure having a tunnel junction, and a controller and logic integrated with and/or executable by the controller. The logic is configured to reduce a local relative humidity in a vicinity of the tunnel junction by passing a current through the tunnel junction for at least a period of time that the tunnel junction would otherwise not have a current passing therethrough. A method according to one embodiment includes determining a relative humidity in an environment of a tunnel junction that is part of a magnetic structure and selecting an operating current from a range of allowable operating currents based on the determined relative humidity. The selected level of the current is high enough to heat the tunnel junction to a temperature which reduces a local relative humidity in a vicinity of the tunnel junction.

  • Patent number: 7948711
    Abstract: A system, a method, and article of manufacture are employed to clean the input/output transducers on tape drives, verified by the tape drives reading alphanumeric information from data tracks and servo tracks of a cleaner tape. An aggressive cleaning frontcoat section of the cleaner tape can be used to provide additional cleaning action, and the cleanliness of the data read elements, data write elements, and the servo heads. A less-abrasive cleaning section may be used to clean less difficult types of contaminants. In this manner, the cleanliness of the data read elements, the data write elements, and the servo heads can be verified. A cleaning section may also be used as a leader section of a self-characterization section. Alternatively, a magnetic data tape section may be included for self-characterization.
