Abstract
Abstract Access to a complete data base stored on optical disk media is limited to portions of the data base to which individual users are entitled by provision of an additional code on the optical disk, indicating the portions of the data base which the customers may access. The disk reader comprises an additional reader for reading the additional code and means for preventing access to other portions of the data base. The additional code may be conventional bar code.
