The problem is that it will only be "intuitively obvious" as long as there
people around who remember that there were once magnetic tape recorders, as
well as some of the details about how they worked. You can't examine a
of recording tape and see anything about it that suggests it contains data
the form of varying magnetization of microscopic particles...and even
that won't tell you about details such as biasing.
Probably the only form of "inuitively obvious" data storage is the shellac
78...you can run your finger along the groove and faintly hear the recorded
sound! OTOH, there is nothing about a CD that tells you it contains data,
let alone the complicated algorithms used to extract that data...
