Why are HDD platters harder than the floppy/ZIP discs?

Yep.

it was the answer for years on stiction,

And you are so stupid that you didnt even notice that hard drive
platters dont have the magnetic material glued to the platters at all.

I am one of many who accepted that.

Because you dont have a clue about how platters in hard drives are actually done.

The heads use lead to write to the platters? Your kind of a jerk and
I'm done with your replies I have followed your post and did have a
bit of respect for you, but man that's gone.

I noticed your one of those to stupid to use a spell checker.

Take the last word, I won't be seeing it.

The magnetic material isnt glued to the substrate, ****wit.

Its vaccuum deposited onto the substrate instead.

Only in your pathetic little drug crazed pig ignorant fantasyland, ****wit child.

Two grammar mistakes in a one-line spelling flame is pretty impressive.

I normally try to avoid these sorts of post, but this one was just /too/
tempting!

Yeah, absolutely classic footshot |-)

I believe that its called laminar air flow

Fraid not.

Don't want to get caught in the flame wars but
thought some might be interested in the following:

Back in the days when the magnetic material was stuck on aluminum platters

That was never the case. It was always vaccuum deposited onto the substrate.

and lubricant was used Seagate outsourced the coating of the platters.
When they had a disconnect between the number of platters
needed and the number being produced their incoming inspection
department rejected most of the incoming as being out of tolerance.
The platter manufacturer took the rejected platter back and shoved
them on the shelf.

Webopedia quote:

Traditionally platters are made of a light aluminum alloy and coated
with a magnetizable material such as a ferrite compound that is
applied in liquid form and spun evenly across the platter or thin
metal film plating that is applied to the platter through
electroplating, the same way that chrome is produced.

Pity that ignores sputtering. Wikipedia does it much better.

As they did it.

As they did what ? Stupid not quoting any of the context.

This is the way the company manufactured Seagate's
platters in the early days, ST225 timeframe.

'Apparatus for manufacturing rigid computer memory disc substrates -
Patent 4620359' (http://www.freepatentsonline.com/4620359.html)

Doesnt even discuss how the magnetic material is applied to the substrate,
in fact it says very explicitly that that step isnt covered by the 'invention'

With the present machine, the disc exits the manufacturing process as
a finished disc substrate, ready to go into wet processing for the
depositing of a magnetic coating. Such wet processes are well known to
those skilled in the art and are not part of the present invention.
Substrates made by this invention could just as easily be coated by
conventional magnetic oxide or by plating or depositing processes or
could even be used in applications entirely different than magnetic
coating or memory use.

Your choice. You made the statement that vacuum deposition was the only way.

You're lying now. I never ever said anything like that.

Seems that the patent holders know of several others and specifically
mention that the wet process is well known to practitioners of the art.

And I rubbed your nose in the wikipedia article which says that there
is more than one way of doing the magnetic coating, and that did NOT
include your stupid pig ignorant claim about it being glued to the substrate.

Are you a practitioner?

Dont need to be. Even someone as stupid as you can use the net to work out how its done.

Hello, Rod:

Please, note that the full headers of "edfair's" messages, indicate he's
posting via "vBulletin USENET gateway" -- which is a Web site, I suppose.

It's possible, "vBulletin" doesn't support proper newsgroup conventions,
perhaps?

He did however quote properly after that.

That does NOT say that it was never done any other way, ****wit child.

Must be great to be 13,

I'm old enough to be your father and quite likely old enough to be your grandfather thanks, ****wit child.

knowing all the answers

Never ever said anything even remotely resembling anything like that either, ****wit child.

without knowing all the questions,

Mindlessly silly.

and the rest of the world is stupid.

Just fools like you, ****wit child.

I would have thought someone as brilliant as you would
have understood the "glue" as a metaphor for bonding.

Never ever could bullshit its way out of a wet paper bag.

Perhaps you could post you IQ for us,

Just how many of you are there between those ears, ****wit child ?

or your CV, and perhaps a job history.

None of your business, ****wit child.

I am posting through the HTFC site.

More fool you, ****wit child.

More direct, less clutter.

And cant quote, ****wit child.
