[net.micro] floppy disks- abrasive disks?

  ...just responding to a message I just read that memorex disks 
are "very abrasive" ...
   how abrasive is abrasive?  I've been using a pair of shugart
drives which have been used daily now for 6+ years; my main disks
are all memorex (at $2 apiece, that's what I buy)... I've also
used some really bad and questionable disks.
  what I'm getting at is that my heads have seen quite alot
of use on abrasive disks and work still flawlessly, so I'm not
sure if abrasiveness is really a worry.
  such incoherence.. .
