摘要：
When recording HD video signals, twice the number of tracks are used as compared to recording the conventional NTSC video signals, and video signals are recorded in the audio sector. HD video signals are encoded with the same number of checks as the error-correcting code of the present video signals, with the number of information symbols being increased. When recording HD video signals and present video signals, these signals are encoded so that the shortest recording wavelength is the same with either signal.
