Invention discloses a playback device and method. The device comprises a plurality of means. A playback means plays back a removable data medium on which a video image is stored in one file. A storage control means stores the size of the file of the data medium, the names of all files and the absolute address corresponding to the video content when playback of video content on the removable data medium stops and when the data medium is removed. A determining means determines, when the data medium is reloaded and video content is played back by the playback means, if the data medium is identical to the removed data medium by reading the size of the file and names of all files stored in the storage medium. The control means continues to process playback of video content based on the absolute address stored in the storage means when the determining means determines that the data medium is identical to the removed data medium. |
