This invention provides method and apparatus for controlling a reproduction speed of an optical disk, which detects the condition of an optical disk and changes the reproduction speed automatically to a pre-determined speed corresponding to the detected disk condition. The method according to this invention comprises the steps of detecting the condition of an optical disk through the characteristics of an RF signal reproduced from the optical disk; adjusting the reproduction speed of the optical disk to a pre-determined speed appropriate for the detected disk condition. This invention enables a user to select the disk speed appropriate for the present operation condition under the possible maximum reproduction speed according to the type of optical disk, and eliminates the delay time caused from gradual speed reduction due to error correction failures at each speed by decreasing the current disk speed to the appropriate speed corresponding to the detected disk condition in advance before frequent reproduction errors occur.
