<p>A magnetic tape recording format and recording/reproducing apparatus in accordance therewith, wherein a first information signal is recorded as a first type of parallel slant tracks having a predetermined space between each slant track, and a second information signal is recorded as a second type of slant tracks having a narrower width than the width of the first type of slant tracks on either side of each of said first type of slant tracks. Furthermore, two of said second type of tracks are positioned between each one of the tracks of said first type. Additionally, the azimuth angles of the tracks of said first type alternate between different predetermined values for successive tracks, and the azimuth angles of the tracks of said second type are both different from the azimuth angle of the track of the first type which is positioned between them, and also different from the azimuth angle of the track of the second type which is positioned next to them in the space between the tracks of the first type. This format is particularly advantageous for use in the consumer rental market since it allows one tape to provide both a high definition television signal and a standard VHS signal.</p> |
