“…[1][2][3][4][5] As a means of increasing the data storage capacity, several technologies have been reported, such as holographic technology, 6,7) near-field technology, 8,9) multilayer technology, [10][11][12][13][14][15][16] and others. [17][18][19][20][21][22][23][24] Among these, multilayer recording technology is a promising approach because it can utilize most technologies of the Blu-ray Disc™ system that is already in use as a commercial technology. 25) Because many recording layers are stacked in a supermultilayer disc, the intensities of the reading and recording lasers are attenuated at the deeper layers.…”

As a means of increasing data capacity, the multilayer optical disc is a promising approach. Because the recording layers in multilayer optical discs must have a high transmittance, they are commonly made of transparent oxide films. Moreover, the recording layer must have sufficient long-term reliability for data archival. In this work, a recording material with high transmittance and long-term reliability for use in super-multilayer discs was investigated. This paper clarifies the recording mechanism of GeBi oxide material and proposes a suitable material design that satisfies the abovementioned characteristics. Furthermore, experimental results of recording on super-multilayer discs based on GeBi oxide recording material are presented.

“…Several high-density optical disc techniques have been proposed to reduce the media cost, including volume holographic memory, [3][4][5][6] a super-resolution head, [7][8][9][10][11][12] 3-beam optical heads with a crosstalk-cancelling circuit, 13) multilayered technology for optical discs, [14][15][16][17][18] and a two-photon recording technology. [19][20][21][22] However, these approaches require additional components, such as new optical heads, or disc fabrication processes.…”

Ref. [4] and Ref. [5] in that only the easy-axis anisotropy term is present whereas in our earlier work an easy-plane anisotropy term Was used in addition. In spite of the seemingly small difference between eq. (1) and the Hamiltonian used by Dynamical behavior of solitary waves in the form of kinks in a one dimensional driven damped ferromagnetic spin system is analysed. The Landau-LifshitzClilbert equation for this system is solved exactly. A balance between the effect of the diive field and that of the damping is found to be possible: stationary motion of the kink results with a constant velocity which is proportional to the product of the external magnetic field and of the Gilbert damping constant. The motion of the kink is accompanied by a constant and uniform precession of the spins.
