Using Your CD Drive
CD Media Description
CD Media Description
CDs, which can be CD-ROMs, CD-Rs, or CD-RWs, are 120mm (4.7
inches) in diameter, and use one data surface with a capacity of 600
megabytes. The data surface contains pits and flat spots arranged in a
continuous spiral track, which is read at a constant speed. You may
access files and data stored on a CD, but you may not write files or data
to a CD.
CAUTION Handle CDs by the edges only. Always be sure a CD is either in the CD
drive or its protective case when not in use. This will reduce the chance
of exposing the disk surface to dust. Over time, dust reduces the
reliability of the read head in the CD drive.
Caring for CDs
Observe the following guidelines to help prevent data loss and prolong
the life of you CD and CD drive:
• Use CDs in a clean environment to prevent dust particles from
scratching disc surfaces.
• Store CDs in a cool, dry place to prevent moisture and heat damage.
• Do not try to clean the surface of a CD with cleaning solvents, as some
cleaning solvents may damage the disk.
