ABSTRACT:
Digital videocassettes are encoded by punching out breakaway tabs to permit a sensing mechanism on a recorder to identify key characteristics of each cassette. The encoding can be changed when the breakaway tabs are carried by an insert that can be remvably affixed to the cassettes. By employing such an insert, a number of problems are avoided such as possible contamination of the cassette and/or recorder by loose tabs. The tabs of the insert do not need to be breakaway when the inserts are initially formed to provide desired codes.
