Using Your CD-ROM Drive
CD-ROM Drive and CD-ROM Media Descriptions
CD-ROM Media
CD-ROM discs are 120 mm (4.7 in.) in diameter, and use one data surface with a capacity of approximately 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-ROM disc, but you may not write files or data to a CD-ROM disc.
CD-ROM data discs are identical to audio compact discs (CDs) except that they store computer data and information.
Handle CD-ROM discs by the edges only. Always be sure a CD-ROM disc is either in the CD-ROM drive or its protective case when not in use. This will lessen the chance of exposing the disc surface to dust. Over time, dust reduces the reliability of the read head in the CD-ROM drive.
Caring for CD-ROM Discs
Observe the following guidelines to help prevent data loss and prolong the life of your CD-ROM discs and drive:
•Use CD-ROM discs in a clean environment to prevent dust particles from scratching disc surfaces.
•Store CD-ROM discs in a cool, dry place to prevent moisture and heat damage.
•Don’t try to clean the surface of a CD-ROM disc with cleaning solvents, as some cleaning solvents may damage the disc.
You must mount the disc after loading it into the drive. Refer to the section “Mounting and Unmounting a CD-ROM Disc,” later in this chapter, for instructions about mounting a disc.
