Yes, seven platters. Reminds me of the old 12 inch winchester

the removable 10? platters.
How did they manage a removable platter in a Winchester drive? It
would
seem like removing the whole sealed unit would leave nothing but a
circuit board behind...
You're showing your lack of age.
I may be showing my ignorance, but I'm not showing my lack of age. I
was in high school when IBM introduced the Winchester drive.
That was a pun figuring you asked because you're too young to have
been
in the computer industry at the time to be familiar with that old
hardware.
Now after giving you links and pics about the HDAs, suddenly now you
know about them. (rolls eyes)
The whole platter assembly was removable. It came out with a
plastic
bell that you could store separately hence you could replace
"drives"
(well, the platter packs since the "drive" was the washing machine
that
stayed in one place).
HDD platter packs:

That one you inserted the pack into a "drive" (about the size of a
small
washing machine), twisted on the handle, removed the plastic shell,
and
closed the drive. As to its size, see the comparison he
Not a Winchester. I was very familiar with several families of
removeable disk packs -- none of them Winchester.

Rack-mounted sliding HDD:

That one only had 1 or 2 platters, the rack-mounted drive slid on
rails,
and you plopped the platter set into the drive (the top was the
seal),
and slid the drive back into the rack.
Still not Winchester.
Because of the size, thickness, and weight of the platters,
especially
for multi-platter packs, they were only supposed to be spun up when
stationary. A U.S. sub once forgot to spin them down before leaving
port, the drive assemblies broke lose from the floor bolts, and the
thing went bashing around the room.
The air contamination problem was eliminated by having both the
platters
and head assembly sealed inside a plastic shell that you twisted
into
the drive which made electrical contacts to control the heads.
Where
you screwed the pack into was the motor to spin the platters. See

Think about trying to tote one of these with your laptop.
History of magnetic drives

OK, now we've gotten to Winchester drives -- and yes, the answer
turns
out to be the motor and drive electronics were all that was left when
you pulled the pack.
Winchester became a nym for all those type of drives whether
or not the heads were included or not in the earlier models.
Wrong.

Just like using Kleenex for facial tissue, the term didn't get used
across
many
types of products until the defining product was introduced and widely
used.
Wrong.
I didn't have to read the part that mentioned "The name stuck in the
USSR, Hungary and possibly other countries as an umbrella term for all
hard drives; it is still in wide use today." Happened, too, in the USA.
Guess you didn't have many contacts back then outside your employer.
Wrong.

Wow, what a great conversationalist you ... aren't.
You don't qualify.
