PROBLEM TO BE SOLVED: To solve problems of a conventional information recording and reproducing devices that cannot have sufficiently obtained a sense of reality, a stereoscopic sense and convenience of information at reproduction of the information because the conventional information recording and reproducing devices have had no information about accurate positions such as a depth of a sound source and an object and recorded audio information and image information or the like one-dimensionally or two-dimensionally. SOLUTION: Information about positions of the sound source and the object is added to audio information and image information or the like and the resulting information is recorded. In the case of reproducing the sets of information above, the attached information about the positions is effectively utilized. For example, in the case of the audio information, position information is added to each recording track by each musical instrument and a different propagation characteristic is provided to each track to generate a sound field with a depth at reproduction. |
