Abstract
The vibration level of a CD-ROM disc is determined in a computer system by installing the disc onto the disc drive. The disc is spun on the disc drive up to an identification speed. The table of contents on the disc is read to determine by disc serial number that the disc is a data disc. Also, the serial number is compared with a file stored in memory to determine that the data disc has been previously tested. The system memory also provides testing information indicating a speed for operating the identified disc without noticeable vibration. The disc drive then operates the identified disc at the indicated speed.
