Abstract
An in-line double gap head ( IDG head ) has been developed for the electronic still camera system. Excellent performance of the IDG heads can be achieved. The cross-talk level is about -45 dB and the carrier to noise ratio ( C/N ) is about 60 dB, which is at least +3 dB better than that of conventional ferrite heads. The IDG heads can record on metal powder media with gap depth as large as 10 µm, resulting in high tolerance of wear ( the wear life is 1000-5000 hours ).
