A write drive circuit provided for every write word line supplies a data write current to a write word line of a selected row, and supplies a magnetic-field canceling current to a write word line of an adjacent row in the opposite direction to that of the data write current. A resistive state of the cell controls a conductive decay rate of the cell. Concentration of mechanical stresses may be reduced due to this configuration. The double clock frequency oscillation circuit receives the control voltage for generating the first clock signal with adjustment phase. An apparatus for writing data to a tape storage medium, a tape storage medium, a tape cartridge are also provided.
