Abstract
An expiration configuration is encoded into non-volatile memory embedded in media, such as a tape cartridge. The encoded expiration configuration specifies if the media is expired and the action to perform if the media is expired. The action may be performed by an application that reads the encoded expiration configuration or by a media device hosting the media. An expiration data for the media may be stored in the encoded expiration configuration or in an external data record.
