Proper Disk Care

• Do not touch the metal part of your floppy disk
• Hold CD ROMs by the edges - Never touch the surface of the disks
• Don't bend, or drop disks.  Keep them dry and clean.
• Keep them out of direct sunlight and away from heat or freezing temperatures.
• Never pu them on top of your computer, monitor, microwave, TV, or near any magnetic field.  Disks are formatted magnetically and exposure to magnetism may make "alphabet soup" of the information that was on your disk.
