All the screws are not visible, some are hidden under labels
and stickers. Takes about ten minutes to completely
dissemble, worth it for the magnets.
The magnets must be buried so deep as not to attract anything.

Bill.

Shielded by the steel case.

Right.
Bill.

The 2 magnets, 1 on each side of the voice coil are glued to the
2 mounting brackets which are made of Mu-Metal which is a
magnetic shielding material.

All this talk of hard drive disassembly and salvaging strong magnets
talk motivated me to take an old drive apart. No problem at all
pulling
the cover, but somehow I can't seem to find these magnets or even
that
voice coil thingy.
Maybe someone can point it out on my drive?

Here's a cover off top view:

Else maybe it's somewhere underneath:

Sorry Ron, I just don't recognize that drive at all, Maybe you
could give us a make and model.

Rene

Fujitsu Limited Model M2235AS [21 Mbytes] (circa 1987)
It was the hard drive on my first PC. G

Sorry, I was just kidding around posting that.
Clearly no super magnet/voice coil technology in that drive..

Well it kept me guessing, :-) I kinda figured it was a vintage drive
but back then I never opened up many drives so wouldn't recognize it
anyway.

On page2 here, it looks like a rotating motor somehow
moves the arm. The mechanism isn't clear.

Ah well, if you're really interested in archeology I could take more
photos of the drive. :-)


The black thing sticking up between the Y shape is a stepper motor pully.
There's a steel band wrapped around it and connected to each side of the Y.
When the motor rotates, the lever moves.
The steel band has three leaves. Two outer ones go to one side of the Y.
The third in the middle goes to the other side. That way, you can
get from one end to the other without having the band overlap anywhere.

Won't be the usual big magnets in that drive.
