Can Disks Be Mailed?
Should disks be mailed, and if so, what is the proper way to mail them?
Disks can be mailed, as long as they are enclosed in a snugly fitting, rigid package. Many office supply stores sell padded jackets (called mailers) especially made for 5¼-inch disks. Also, for what it's worth, many users write a message on the outside of the mailer, to warn mail handlers that the package contains a magnetic recording which can be damaged by electromagnetic fields.
