A magnetic storage element capable of recording with a small magnetic field and retaining information stably and a recording method thereof, and a magnetic storage device having the magnetic storage element and capable of simplifying a drive circuit thereof are provided. Compared to the classical support by conical-roller bearings, a substantially lower frictional moment and substantially lower bearing wear are attained by the bearing arrangement of the present invention. The reset transistor includes a gate, a source connected to one of the metal plates and a drain connected to the other of the metal plates. The wavelength range of each laser beam covers at least two grids including neighboring grids. The present invention also includes improved methods for determining the thermal stability of binding complexes. The digital rights management provider may digitally sign the license and may transmit the signed license to the digital content distributor.
