Taking care of floppy disks
Follow the care instructions that came with your disks, and
remember three key points:
n
Keep floppy disks away from magnets. Because
information is stored on the disk in the form of magnetic
signals, a magnetic field can destroy that information.
Televisions and monitors, telephones, loudspeakers, and
certain kinds of lighting fixtures all contain magnets.
n
Protect disks from extremes of temperature and humidity.
n
Do not open the disk’s metal shutter. Touching the disk
inside the shutter could damage it.
