Subject: Floppy Disk Warning!!!

This comes third hand from a materials scientist in Silicon Valley
who is working on hard disk recording methods.

I am not sure of the actual techical accuracy, but the gist is

       AVOID ELEPHANT MEMORY DISKS - THEY WILL SCREW UP
               YOUR HEADS.

The disks have a large amount of what I think he called Alumina.  Although
the disks do not seem to have many errors, they have an interesting side
effect.  The alumina(?) is used to reduce cost and increase disk
reliability, but too much will erode the heads of disk drives.
The Elephant disks have too much.

I am trying to get a more specific and accurate description of
the problem and will post it as soon as I decipher it.

In the intevening weeks, simply beware of Elephehant memory disks.
