You appear to be confusing the recording encoding method
with the recording medium.
There are both analog and digital methods of recording.
There are both magnetic and optical (and mechanical) media.
It would appear that digital is a more reliable method of
encoding data than analog. For the obvous reasons that it
is easier to decode semi-degraded information because
you know what to expect, etc.
I have first-hand experience to show that field-writable
optical media are not necessarily reliable. And certainly
not as reliable as mag tape (whether analog or digital).
(And don't forget that the hard drive your computer is
using right now is magnetic.)
