A few experimental digital VTR devices have recently demonstrated the technical feasibility of digitalization. However, standardization is vital for digital VTR proliferation. Consequently, more detailed work should be continued focusing on the optimum tape format, channel coding and picture coding. Introduced here will be some basic results on our experimental digital VTR, especially concerning the magnetic recording and error correcting techniques.
