Abstract
PURPOSE:To attain a long period recording or reproduction good in a stability in the travel of a tape by specifying the positions of the respective constitution heads of a first head group and a second head group respectively provided with three heads adjacently disposed to a rotating drum. CONSTITUTION:The respective constituting heads 24, 26, 28 of the first head group are situated at an opposite side to the respective constituting heads 30, 32, 34 of the second head group with respect to the center of the drum and the respective constituting heads 24, 26, 28 sequentially have a first azimuth angle, a second azimuth angle and the first azimuth angle and the respective constituting heads 30, 32, 34 of the second head group have opposite azimuth angles to the constituting heads 24, 26, 28 of the first head group opposing thereto by 180 deg.. The constituting heads of the first head group and the second head group are selectively used to execute the recording or the reproduction of a standard or a compression, so that a recording track in which the azimuth angles are alternated can be simply realized and accordingly, a signal processing circuit at the time of recording and reproducing can be simplified. The six heads in the total number of both the head groups are selected and used, thereby, a 1/6 compression can be realized.
