The search unit 112 searches the information indicating the free capacity of each information recording medium from the copy / move management information stored in the management information storage unit 110. The search unit 112 also functions as a free space information generation unit that generates free space information for displaying each free space of the information recording medium corresponding to the search condition in a predetermined order. When the above-described replication / movement management information update processing is performed, the free capacity of each information recording medium is accurately reflected in the replication / movement management information, so that it is possible to perform a high-accuracy free capacity search. it can.

  FIG. 10 shows the free capacity information displayed as a GUI on the display device 131. In the GUI shown in FIG. 10, information recording media capable of recording content data having a desired data capacity are displayed in ascending order of free capacity. The display order is arbitrary, and may be, for example, the order in which the free space is large. Accordingly, the user can easily specify an information recording medium capable of copying or moving desired content data by checking the free space information.

  Instead of inputting the data capacity required for the content data in the numerical value input area, the user may specify the content data to be copied or moved. In this case, the search unit 112 automatically detects the data capacity of the designated content data and searches for an information recording medium that meets the search condition setting.

  In the above-described embodiment, the information recording apparatus 101 is a stationary apparatus. However, the information recording apparatus 101 may be an information recording apparatus other than a stationary type such as a DVD camera, a mobile phone, or a portable video reproduction apparatus.
