  • Publication number: 20200159433
    Abstract: A linear tape file system (LTFS) maintains a series of indexes, and an incremental change dataset, that records incremental changes that have taken place in each new index over the previous one, as each new index of the series is created. Upon receiving a command to roll back the file system from a current generation to a target previous generation, a generation control module applies information in the incremental change dataset to the current index. In this way, the current index is restored, at least functionally, to the state it was in when the target generation was created, thereby effectuating the rollback of the file system to the target generation.

  • Patent number: 10651658
    Abstract: A foreign object detecting device includes first and second coils, the winding directions of which are the same, and a foreign object detecting circuit. The foreign object detecting circuit outputs a first detecting signal having a first predetermined waveform to a first terminal of the first coil and outputs a second detecting signal having a second predetermined waveform, which has the same polarity as the first predetermined waveform, to a third terminal of the second coil to cause magnetic fields generated from the first and second coils to repel each other. The foreign object detecting circuit measures an amount of change of the impedance value of the first or second coil which is caused by the presence of a foreign object. When the amount of change exceeds a predetermined value, the foreign object detecting circuit determines that there is a foreign object above the first or second coil.
