Epson 20 - Manual (Page 70)

Do not place anything on top of your diskettes and be sure they
do not get bent. A diskette does not rotate properly in the drive
if it has been damaged.
Carefully label your diskettes. Attach labels firmly but gently, and
only along the top of a diskette (next to the manufacturer’s label).
Do not stick several labels on top of one another; too many labels
can make it difficult to insert and remove the diskette in the
drive.
For 5 1/4inch diskettes, it is best to write on the label before you
attach it to the diskette. If you need to write on a label that is
already on a diskette, use only a soft-tip pen, not a ballpoint pen
or a pencil. Always indicate the drive and density type on the
label.
Store diskettes in a proper location, such as a diskette container.
Do not store diskettes flat or stack them on top of each other,
When you are not using them, keep your 5 1/4-inch diskettes in
their protective envelopes.
Inserting and Removing Diskettes
To insert a diskette into a 5¼-inch drive, hold it with the label facing
up and and the read/write slot leading into the drive.
