because they have high rewrite rates. Sony tapes are bad since
Sony introduced Hi-8.
Some years ago someone from MIT wrote that MIT is using
thousands of cartridges a month and they use cheap Fuji Video tapes
(Do not use HI-8 ) I know that US-type video tapes are worse
that european type tapes because the higher quality is not needed
for the lower resolution of the US TV system, but you may
Two other possibilities may raise your problem:
- The heads need more cleaning
To fix this you have to be very carefully.
Open the drive and use a Q-Tip with *.
Carefully put the Q-Tip on the head drum
(at the point where the little heads are visible)
Then carefully turn the drum...
- The * roller at the capstan drive is bad
I had a drive where this roller had fissures
and caused jitter.
