A head arrangement on a drum assembly includes two groups of video heads, each group having N video heads wherein N is a positive integer, the video heads in each group being positioned closely adjacent one another at a predetermined space and the video heads in each group are disposed at different heights stepwise upwardly from the bottom of the head drum assembly. A second embodiment of a head arrangement on a head drum assembly includes N pairs of video heads arranged in such a manner that each pair of video heads is angularly separated from one another by 360 DEG /N wherein N is a positive integer, each of N pairs having a first and a second video heads which are disposed adjacent each other and the second video head in each pair is disposed at a predetermined height upwardly with respect to the first video heads in each pair from the bottom of the head drum assembly.
