Abstract
An optical article for playback in a player includes a first file comprising a first control logic; and a second file comprising a second control logic. The first file is configured to direct the player to play a first content data stored on the optical article, when the first control logic is read by the player. The player is directed to read the second file if the player cannot read the first file. The second file is configured to direct the player to play a second content data stored on the article when the second control logic is read by the player. The optical article includes a mark containing an optical state change material disposed on at least a portion of the first file, wherein the mark is in one of a first optical state or a second optical state, and wherein the first control logic can be read only when the mark is in the second optical state.
