Folks -
I believe the word 'tape' holds the clue - insofar as I know from the EMI recording sheets in my files, EMI never used film on sessions. They *did*, however, use 4-track, 1/2 inch tape to record opera as early as 1959. And in the case of these Klemperer-Wagner sessions, they are probably referring to one-inch tape for an 8-track Studer, not 35-mm film.
