Abstract
A technique for setting a speed of an optical disk player according to a condition of an optical disk performs the steps of: setting a speed of the optical disk and an interval for measuring the condition, reading data recorded on the optical disk at the predetermined speed and at the same time measuring a data transfer rate, an access time, a compared value with respect to a reference value and an error of the disk of the predetermined interval, displaying the condition of the optical disk and the measured speed thereof on a screen, and setting a desired speed with reference to the condition and speed displayed on the screen. Thus, the speed may be set according to the condition of the optical disk, to check stability of the optical disk and enhance the condition of the optical disk.
