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

Wrong. There was no ramp initially, that came later to avoid
stiction which happens due to the very smooth platter and head


No, it was the glue (used to keep the magnetic media on the aluminum
platters), would get sticky when hot, when the heads parked themselves,
the glue would cool down and the heads would become stuck.


Utterly mangled all over again. There was never any 'glue
(used to keep the magnetic media on the aluminum platters)


I had read and been informed that it was the glue,


And you're so stupid that you cant work out what is mindless silly **** and what isnt.

apparently it was due to "lubricants used to coat the platters"

Yep, for when the heads did land on the platters. They dont anymore.

And you are right about the Ramps they are addressed in
the link as well - I do need to open up a new HD, but don't
have a bad one; lot's of old drives, less than 2gigs mostly


Yeah, tho the newest of those may well have the ramps.

No point tho, wikepedia is right on that and you can find plenty of
documentation on them from the hard drive manufacturers too like
