ABSTRACT:
A recording drum assembly comprises a cylindrical drive shaft 1, a drum 2, and an annular disc 4 of resilient material, such as spring steel, located between the drive shaft 1 and drum 2 and substantially coaxial with the drum 2. The disc 4, by elastic deformation when engaged by the drive shaft 1, provides axial alignment of the drum 2 and drive shaft 1. A portion of reduced diameter may be provided on the drive shaft 1 to facilitate removal of the drum 2 from the drive shaft. Furthermore, the annular disc 4 may be used to support the drum 2 during machining of the drum outer surface to ensure coaxial alignment.
