Carts are just a plastic box with quarter inch tape in them. That went for Fidelipacs, Scotch Carts or any others. Any format is determined by the recording device, not the tape.
Very true. What I was intending to convey on the line of the 4 track consumer market carts was that most of the carts I saw in K-Mart many years back were more generic no-name plastic boxes, but maybe 1% of the carts were indeed Fidelipac carts, brand name, everything.

Broadcast carts did not have a metallic foil splice. They used plain splicing tape. Those of us who rewound or wound our own carts simply bought the special cart tape that had the right lubrication for the mobius loop, used a cart winding device with tape length measurement and spliced the same way we did with reel tape. Many of us used splice finders so we did not record over the splice; the trick was to start recording right after the splice.
Might have been true that the more expensive cart machines did use tone cueing, but the first cart machines we had in a station where I worked weekends, in the mid-1960s, a low budget operation, the first cart machines they had were no-name units which used the Viking “****-the-pinch-roller” decks and they did indeed use a strip of metallic foil to stop the machine on recue.
I have no idea where the machines came from, or who made them, but I think they were made in some low budget operation.
That might not have been the practice with the bigger companies, but the foil was in the carts, and the machines did not have tones.
I do hope you did not actually make a Mobius loop for your tape reloads. That won’t work. I am sure you really meant an endless loop.
I did finally work at a few locations which really had a Spotmaster tape rewinder, but for many years, I used a reel to reel deck and simply timed the tape load. Necessity is the mother of invention. National Audio and I were good friends, so to speak, as I bought a lot of tape and cart parts from them.
The Spotmaster 500/505 desk top cart machines, with the lift up lid, were a great splice finder. I had one station where the evening guy was the FM transmitter watcher, and one of his evening duties was to gather up all the pulled carts, bulk erase them and then use a Spotmaster to cycle the carts until the splice went by the heads.
