    摘要： A negative electrode for a rechargeable lithium battery includes a current collector and a negative active mass disposed on the current collector. The negative active mass includes a negative active material including a lithium vanadium composite oxide and a crystalline structure aid for inhibiting deterioration of a crystalline structure. The negative active material can inhibit an irreversible crystalline structure change during charge and discharge, and does not incur decomposition of an electrolyte resulting in improvement of a cycle-life of a rechargeable lithium battery.

    摘要： A hard-disk drive. The hard-disk drive includes a magnetic-recording disk including tracks on which a plurality of patterned bit-cells that are isolated magnetically are aligned at predetermined alignment pitches. The hard-disk drive includes a magnetic-recording head which is configured to follow tracks, and to write and to read data. The hard-disk drive includes a signal-processing unit which is configured to generate a recording signal based on a write-clock signal with cycles corresponding to alignment pitches of patterned bit-cells, and to output a recording signal. The hard-disk drive includes a phase-detecting unit which is configured to detect a phase of the write-clock signal when the magnetic-recording head reaches an end point of a predetermined range. The hard disk drive includes a determination-processing unit which is configured to determine success of data writing based on a difference between an expected value and a detected value of the phase of the write-clock signal.
