Claims

[Claims for Utility Model Registration] (1) A fixed drum, a rotating drum above the fixed drum, and a rotary drum arranged on the rotating drum so as to record different information signals in areas separated in the width direction of the magnetic tape. Two sets of rotating magnetic heads arranged at predetermined angular intervals in the circumferential direction and arranged in the axial direction of the rotating drum at different heights, A rotating magnetic head device for guiding the running of a magnetic tape, wherein a first set of supporting members supporting a first set of rotating magnetic heads and the first set of supporting members have different sizes; A second set of support members supporting two sets of rotating magnetic heads are attached to the upper and lower surfaces of the rotary drum with the rotary drum sandwiched therebetween, and a second set of support members supporting two sets of rotating magnetic heads is attached to the upper and lower surfaces of the rotary drum. At a position that partially covers the outer periphery of the large support member,
A common horizontal position adjustment hole for the rotating magnetic heads of the first and second sets is bored in a position that does not overlap the outer periphery of the smaller support member of the first and second sets. A rotating magnetic head device characterized by: (2) The rotating magnetic head device according to claim 1, wherein the first set of support members and the second set of support members are smaller in size than the latter. . (3) The rotating magnetic head device according to claim 1, wherein the first set of supporting members and the second set of supporting members are smaller in size than the former. .
