The present invention aims at providing a playback apparatus that performs playback control so as to prevent, in playback of content recorded on a recording medium, a decline of the value of the recording medium and content. In the case of having failed in reading of content data from the recording medium, as well as in the case of determining the necessity of content data replacement, the playback apparatus of the present invention acquires, from the distribution server, pieces of partial content data corresponding to locations at and following the reading failure, as well as pieces of replacement content data corresponding to locations whose data needs to be replaced. The playback apparatus plays back content data recorded on the recording medium and partial content data and replacement content data acquired from the content distribution server.
