Abstract:
1. An information processor device comprising: a lighting unit for irradiating electromagnetic waves to a storage medium which stores data in a plurality of three-dimensionally placed small areas, the data being obtained by applying a two-dimensional inverse Fourier transform for data placed on an axis of a first coordinate and transforming the data onto an axis of a second coordinate; a receiving unit for receiving the electromagnetic waves passing through the storage medium; and a calculating unit for calculating information obtained in the receiving unit and outputting data corresponding to a request from an outside, wherein the calculating unit calculates based on the information obtained in the receiving unit to obtain positional information of the data placed on the axis of the first coordinate, and the calculating unit calculates a one-dimensional Fourier transform for the information obtained in the receiving unit to obtain the positional information of the data placed on the axis of the first coordinate.
