Abstract

PURPOSE:To achieve high-precision assembling easily by fixing a cylindrical fixed drum, which winding the tape around its outer circumference and guides a run of a magnetic tape to a center hole part which has a center through hole worked concentrically with the outer circumference. CONSTITUTION:A cylindrical fixed drum 30 capable of guiding a run of a magnetic tape by winding the tape around its outer circumference is fixed to a center part 32, worked concentrically with the outer circumference, while the lower part of a main shaft 34 is fitted by insertion. In this case, the fixed drum 30 has precise axial height H from its fitting reference surface 38. Then, a rotary head 40 coming into contact with the magnetic tape is fitted to a rotary drum 42, which is fitted in a rotary disk 48. This constitution eliminates the need for work for correction of face run-out movement of the rotary-drum fitting surface and correction of the height from the reference surface, facilitating high-precision assembling.
