The concept of stationary head digital recording has been pushed forwards in the audio domain (S-DAT, DCC). However conventional thin film head technology limits the track density to 500 TPI. We have developed a new head design which allows head stack integration up to 5000 TPI, and shown its ability to record digital video. SUMMARY The main limitation in terms of cornpacity and ruggedness of video recorder is the rotating drum. On one hand digital format enlarges the segmentation choice and allows the realization of a smaller scanner, but on the other hand the need for high data rate requires larger head to tape speed or more heads.
