A recording format has been proposed for a multi-track continuously recorded tape wherein the data is placed byte-by-byte on adjacent tracks with each data byte being offset slightly with respect to the bytes immediately preceding and following it. The data is separated by special marks which are written on the tape. In a specific embodiment of such an arrangement, the tracks are divided into zones with each zone containing three tracks equally spaced across the tape. For example, Zone A might comprise tracks l, 4 and 7, whereas Zone B comprises tracks 2, 5 and 8. With respect to data the zones are meaningless. However, in groups, they are used to identify the previously mentioned special marks or convey special meanings. The special marks preferably include an erase gap, interblock gap and tape marks, for example.
