So why did they use tapes in Star Wars? They have advanced technology. Why would they use something as inconvenient as a tape?
The somewhat obvious answer to that would be that back in the 70’s most forms of recorded medium would be referred to as “tapes”.
(It’s exactly the same as when someone in an 80’s sci-fi film set in the future uses a floppy disk.)
I’m sure people in the future will chuckle at the sci-fi films of today whenever someone mentions “discs” or “hard-drives”, etc.
