A system for tracking locations of portable data storage media. The system
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.
