VHS tape can indeed hold teletext, but most of the time it is of too poor quality to be directly usable.
There is, however,
software that can take this poor quality signal and "fix" it using modern computer hardware. I was successful in doing this with quite a few of my old home-recorded tapes until (a) I ran out of tapes and (b) my VHS machine developed head issues. So I still have everything setup except the player and the tapes!
