Claim:
A data recording/reproducing device, comprising: a position detection unit that detects position information indicating a first position at which data are acquired, and detects position information indicating a second position at which data are reproduced; a determining unit that determines which specific set of geographical information, among a plurality of sets of geographical information defined in advance, the position information indicating the first position detected by the position detection unit corresponds to, and that determines which specific set of geographical information defined in advance, the position information indicating the second position detected by the position detection unit corresponds to; a recording control unit that records the acquired data into a recording medium based upon the specific set of geographical information regarding to the position information indicating the first position determined by the determining unit; a selection unit that selects reproduction-permitted data from the recording medium based upon the specific set of geographical information regarding to the position information indicating the second position determined by the determining unit; and a reproducing unit that outputs and reproduces at least one set of data among the reproduction-permitted data having been selected, wherein: the geographical information is constituted with information related to spatial areas (hereafter referred to as spatial area information) each indicating a specific range containing at least one of the first position and the second position; and the spatial area information includes a plurality of sets of information corresponding to at least a first spatial area and a second spatial area, access by unspecified third parties being prohibited in the first spatial area and access by unspecified third parties being not prohibited in the second spatial area.
