Abstract:
1. A head system for performing azimuth recording on a recording medium by use of a plurality of recording heads, wherein: said head system comprises a first recording head A including a plurality of first magnetic gaps A a positional relationship between said first and second magnetic gaps is so determined that in relation to each magnetization pattern formed on said recording medium by said first magnetic gaps of said first recording head, side edge portions in the formation direction of said patterns are overwritten by said second magnetic gaps of said second recording head, wherein the height of the lower edge portion of the gap A said first and second recording heads are thin-film heads, and a single head chip constituting each said recording head is provided with a plurality of magnetic gaps and wherein said first and second recording heads are mounted on a rotary drum, and each of said magnetization patterns formed on said recording medium is an inclined track, wherein said overwriting is conducted with such a positional relationship that a side edge portion of said magnetization pattern in the formation direction of said magnetization pattern formed by each said first magnetic gap of said first recording head coincides substantially with the center of each magnetization pattern formed by said second recording head and, wherein, as for the height relationship between the gaps A 1 and A 2 , the upper edge of A 1 is at the same height as the lower edge of A 2 , so that when the upper edge of A 1 is at the same height as the lower edge of A 2 side edges of magnetization patters formed on the tape by the magnetic gaps coincide with each other at the boundary therebetween.
