Abstract
An optical article for playback in a player includes at least one sector comprising a first control logic configured to set the value of a first register, the first register having a default value before it is set, and a non-default value after it is set, and a first command to be read sequentially after the sector. The first command is configured to direct the player to play a first content on the article if the first register is set to the default value and to direct the player to play a second content on the article if the first register is set to the non-default value. The optical article includes a mark containing an optical state change material disposed on the sector, 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.
