A method and apparatus to reproduce and/or record data from and/or to an optical recording medium. The method includes detecting a wobble signal from the optical recording medium, predicting a wobble channel state from the detected wobble signal, detecting an information signal from the optical recording medium, predicting an information channel state from the detected information signal. If a damaged section is discovered from the optical recording medium, the information signal is decoded based on the information on the wobble channel state or the information on the information channel state. Accordingly, data can be reproduced more effectively by predicting a channel state of an information (RF) signal and a channel state of a wobble signal.
