Hello, sorry I wasnt here earlier. Do you still need help with this?
Yes please Rob,.
If you look at the cassette you are using
in one corner there is a "tab"
or a locking piece
If you slide it one way it locks
its a security feature so you dont record over the top of a precious tape
If you slide it the other way it will allow you to record
Often there is a padlock symbol to show you which way is which
I hope this answers your question and you click the accept button for me, as this is how I get paid for helping you.
Thanks Rob. The tape was faulty and button missing but found new tape to replace.
All the best. Louis
