Using floppy disks
Your computer does not have a floppy disk drive built in, but you
can connect it to a floppy disk drive. (For instructions, go to the
chapter on expanding your computer system.)
When you connect your computer to a floppy disk drive, you can
use two types of 3.5-inch (89-millimeter) floppy disks:
n high-density disks (marked with the icon Ó), which can hold
up to 1.4 megabytes (MB) of information
n double-sided disks, which can hold up to 800 kilobytes (K)
of information
(The next page explains kilobytes and megabytes.)

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.
