Of course not. But because of the head orientation on Apple disk drives,
the backside of the disk is what actually holds the "side 1" data.

Say for instance you had a bad sector on a "one-sided" diskette caused by
a physical defect and you looked at the front surface of the disk through
the head notch looking for the defect. You wouldn't see it. You'd have
to flip the disk over to see the defect.

But of course, you knew this :)
