Which does rather show your ignorance of the topic!

Ummm.. for some value of "large" and "excellent".

You obviously are unaware that helical recording was invented
specifically for recording stuff where reliability was paramount. We
call it "broadcast"...

(As in what TV stations used for years).

Of course, for any given technology there are *good* implementations
and *bad* ones. However, if *anyone* claims that a given technology
(e.g. helical or linear) is intrinsically unreliable, I'd conclude
that that person is unqualified to offer sound advice.

Bad advice. Consider failure modes...
