The environmental factors to be considered in establishing electronic recordkeeping systems differ in accordance with the volume and the sensitivity of records to be processed. A large-scale recordkeeping operation maintaining great numbers of sensitive records on a large computer requires extensive environmental controls. Conversely, a smaller-scale, noncritical recordkeeping system operating on a personal computer probably involves fewer environmental considerations. However, small systems with sensitive electronic equipment require a minimum level of environmental control to operate reliably. A floppy disk is made of a stable nonmagnetic material, such as mylar, coated with magnetic oxide particles mixed with a binder.
Floppy disks are delicate and require special care.
The recording surface can be damaged, and the information obscured or lost, by fingerprints, dust, spilled liquids, cigarette ashes, eraser dust, and other contaminants. Avoid disk contact with equipment that generates magnetic fields, such as telephones. Avoid writing on a label affixed to a disk or on the jacket or sleeve if the disk is inside. A felt pen can be used sparingly. Protect disks from direct sunlight.
