A system for tracking locations of portable data storage media includes media with a wireless tag storing metadata pertaining to its stored data. The tag is adapted to respond to an interrogatory signal by wirelessly transmitting a signal comprising the metadata, e.g., is a high frequency radio frequency identification (RFID) tag powered inductively to transmit contents of its memory. The system includes a stationary and mobile locators that includes tag readers transmitting the interrogatory signals to the media and receiving the metadata signals from the wireless tags. Mobile ones of the locators include a communication module receiving location data (e.g., Global Positioning System (GPS) data) and sending wireless signals made up of the received location data and the received metadata signals. The system includes a media tracker that receives signals from the mobile locator and determines and stores locations of the media typically along with a time stamp.
