An encrypted content playback apparatus and a playback method suitable for content playback from a medium in which both content that is subject to conventional copy protection and content to which DRAM is applied exists, and a recording medium on which data used in the playback apparatus and the playback method is stored are disclosed. The medium stores information indicating, for each content, whether the content is content subject to conventional copy protection or content to which DRAM is applied. Based on this information, a playback apparatus determines the key to use to decrypt the content.
