I mentioned using Scotch tape for a temporary repair. I neglected to mention that it is VERY temporary. It should allow making a duplicate tape.
There is a special tape that is much more permanent, but is rather hard to locate. There also used to be precut patches that used the special mylar adhesive, but are also hard to find anymore.
It is tricky business with an everpresent likelihood of damage to your videoheads, so unless the tape is really important to you, I would discourage risking a DIY job.
