    摘要: An optical read/write apparatus causes a read/write light beam from illuminating means to strike only one side of an optical storage medium including stacked data storage layers each of which is readable/writeable separately from the other layers. In this case, the optical read/write apparatus operates so that data is read/written from/into a second data storage layer after fully recording a recordable area of a first data storage layer. Thus, light can be shone with uniform intensity across the substantially entire recordable area of the second data storage layer without using a complex read/write system even under such conditions that the transmittance to light of the first data storage layer in the recordable area may vary depending on whether any data is recorded in the recordable area.

    摘要: A recording layer and a flux adjustment layer have different magnetic polarities so that their magnetizations are countervailed at room temperature, with the result that a weakened leakage magnetic flux is released therefrom. A reproducing layer, a reproducing assist layer and an in-plane magnetization layer exhibit in-plane magnetization at room temperature. In a first temperature area having a temperature not more than the critical temperature of the reproducing layer, the reproducing layer 1 exhibits in-plane magnetization so that magnetization of a recording magnetic domain is not copied to the reproducing layer. In contrast, a second temperature area having a temperature rise between the critical temperature and the Curie temperature of the reproducing layer, the flux adjustment layer and the in-plane magnetization layer have reached their Curie temperatures and lost their magnetization; thus, a leakage magnetic flux generated by the magnetization of the recording magnetic domain is copied to the reproducing assist layer that is in a perpendicular magnetization state, and further copied to the reproducing layer. Moreover, in a third temperature area having a temperature rise exceeding the Curie temperature of the reproducing layer, the reproducing layer has lost its magnetization.
