Abstract: Provided is an apparatus and a method of driving an optical disk, and more particularly, to an apparatus and a method of removing radial noise generated when an optical disk is reproduced. The apparatus removing noise in an optical recording medium driver provides a noise processor detecting an error signal from a high-frequency signal output by a pickup when the optical recording medium is reproduced, and removing noise included in the error signal and a second signal processor outputting a pickup motion signal moving the pickup by using the error signal from which noise is removed and which has been output from the noise processor. Through the apparatus and the method, it is possible to solve the problems of a focus drop in a focus servo, and a pickup lens which is confined to a right or left side in a tracking servo, by detecting and removing radial noise from the RF signals which are output from the optical disk.
