Abstract: PURPOSE:To realize the stable running of a magnetic tape by coating a rigid carbonaceous film of Vickers hardness of 3000-5000 on surfaces of the unrotatable metallic tape guides which are arranged on the running path of the magnetic tape. CONSTITUTION:The tape guides 22, 23 which are made of stainless steel, constitute drum entrance and exit guides 5, 6. A stainless steel tape guide 16 is a fixed guide arranged between the drum exit guide 6 and a channel erase head 12. The rigid carbonaceous film 31 of Vickers hardness of 3000-5000 is coated respectively on the surfaces of these tape guides 5, 6, 16 by the vaccum deposition method, etc. In this case, the thickness (t) of this rigid carbonaceous film is approximately 1mum and the surface roughness is 0.5-0.6S. The variance in the frictional resistance of the magnetic tape caused by the repeated running of the magnetic tape is thereby remarkably reduced.

Abstract: PURPOSE:To decrease the number of parts, to reduce cost, to stablize a ground pin and to make a device thin as a whole by installing the ground pin in a drum and fixing this ground pin by soldering. CONSTITUTION:A ground pin 13 is put in with pressure and installed in a fitting hole 10e formed in the peripheral wall part 10c of a notched part 10d in a lower drum 10 and a small diameter part 13a of this ground pin 13 is fixed with a substrate 15 for video signal by soldering. Therefore, a screw with washer is not required and the number of parts can be reduced for the screw. Further, since it is not necessary to control the fastening torque of the screw, grounding can be more easily stabilized. Thus, the cost is reduced, grounding is stablized and the device can be made thin as a whole.
