There were plenty of physical similarities. ALL were helically
scanned tape laid against drum heads. THAT is what made the beta
format family, not the cassette size or shape.

The original was helically scanned PCM coded data stripes. That has
carried through as the method for maximizing the tape available and
the rate at which data can be laid upon it.
The things that have changed are video formats, and signal
conditioning, and a host of other tid bits that just were not
available back when beta first came out. Nothing back then, not IC
chips, not systems, streamed fast enough for an HD datagram, even if
such a thing had been defined back then, and it as yet was not.
