摘要： In an optical information recording medium of this invention, at least one cell including diffraction gratings is disposed on a planar substrate. This cell is divided into n (n is an integer of 2 or more) regions such that each divided region represents one binary data. To read information, light-receiving elements corresponding in number of the number n of divided regions of the cell are disposed to correspond to the respective divided regions. One incident light beam is caused to be incident on the cell. Diffracted light components emerging from the respective divided regions of the cell are received by the light-receiving elements, thereby reproducing data. Thus, information can be recorded at a very high density, and information can be read at a high speed.

摘要： In an optical information recording medium of this invention, at least one cell including diffraction gratings is disposed on a planar substrate. In accordance with exemplary embodiments, a ratio of a line width of the diffraction gratings to a grating pitch of the diffraction gratings is changed based on the data. To read information, an incident light beam is caused to be incident on the cell. Diffracted light components emerging from the cell are received by light receiving elements, thereby reproducing data. Thus, information can be recorded at a very high density, and information can be read at a high speed.

摘要： In an optical information recording medium of this invention, at least one cell including diffraction gratings is disposed on a planar substrate. This cell is divided into n (n is an integer of 2 or more) regions such that each divided region represents one binary data. To read information, light-receiving elements corresponding in number of the number n of divided regions of the cell are disposed to correspond to the respective divided regions. One incident light beam is caused to be incident on the cell. Diffracted light components emerging from the respective divided regions of the cell are received by the light-receiving elements, thereby reproducing data. Thus, information can be recorded at a very high density, and information can be read at a high speed.
