JOHANNES HENDRIK VAN DYK
If you refer to the cassette, the instruction would be that you would have to take a brand new tape and that there should be nothing else on that tape, other than that which you want to record on it.
	In other words you mustn't tape that interview and then other things, that must be the only thing on the tape and then afterwards you would hand over the tape and the procedure as I've mentioned would take place, it would be sealed and kept in safe custody.
