That's what I mean, though, is that my internalized idea of cassette == tape was the one that was wrong. It was one of those words I learned incorrectly as a child based on the observation that everything adults called “cassettes” had magnetic tape in common, not realizing that “cassette” is describing the enclosure instead of the contents and literally means “little box” (case-ette). Nintendo were using it correctly and taught me something in the process and that's why I think it's cool and wanted to share.
