An optical disk driver of the present invention has a pickup for picking up the ID information and the data information recorded on a disk as a radio frequency signal, a demodulator for demodulating the radio frequency signal which is picked up by the pickup into a binarization signal, an interface controller for outputting an instruction signal corresponding to a target track number to be searched, a servo driver for transferring the pickup to the track that corresponds to the target track number, an ID reading circuit which reads ID information indicating the track location from output data from the demodulator, and a micro-computer for outputting a driving signal to the servo driver so as to transfer the pickup to the track that corresponds to the target track number, and for determining whether the ID information from the ID reading circuit corresponds to the target track and outputting an operation-completed signal to the interface controller if the ID reading circuit does correspond to the target track. Thus, track searching time is reduced as the instruction sending/receiving between the interface controller and servo is simplified.
