ABSTRACT:
A magnetic tape recording with a new signal encoding format, apparatus for recording this format and reproducing apparatus for reproducing signals from this format. A standard VHS signal is recorded as a first set of parallel slant tracks having a predetermined spacing between each slant track. A high definition television signal is recorded in pairs of slant tracks of a second type that flank a slant track of the first type and are narrower in width than the slant track of the first type they flank. Additionally, the azimuth angle of the tracks of the first type alternates between different predetermined values for successive tracks, and the azimuth angle of the tracks of the second type differ both from the azimuth angle of the tracks of the first type which they flank, and from the azimuth angle of the tracks of the second type which are positioned next to them in the space between tracks of the first type. This format allows one tape to record both a high definition television signal and a standard VHS signal, which standard VHS signal can be played back using ordinary tape machines. Accordingly, this format provides a way to avoid the problem of having to carry a dual inventory of tapes in a tape sales or rental business.
