Abstract
A head drum assembly has an upper drum having at least two video heads at an outer bottom portion thereof, and a rotor transformer at an inner bottom portion of the upper drum. A lower drum is formed on a boss and has a cylindrical shape with the same diameter as that of the upper drum. The lower drum is positioned under the upper drum. The boss is formed by bending a deck upwardly. A lead line for leading a magnetic tape is formed on the outer periphery of the lower drum. A stator transformer corresponding to the rotor transformer is positioned on a main PCB. A shaft is integrally formed on a main chassis and is installed in the center portion of the upper drum. A motor for rotating the upper drum relative to the shaft is provided. The manufacturing and the structure of the head drum assembly is simple.
