How to clean the roller of video recorder?

The magnetic head on the drum of the video recorder is very fragile. I have seen many cases of breaking the disk with deerskin. It is recommended to use a special cleaning belt. If not, you can gently press the magnetic head with the brand-new 100 RMB, turn the drum, and your fingers can feel the contact between the magnetic head and RMB, and you can see the magnetic powder that has been wiped once or twice.
