An apparatus for recording and/or reproducing information with respect to a disk-like recording medium having a recording surface divided into a plurality of concentric circular zones each including a plurality of tracks with an address recorded thereon at an angular velocity or frequency varying with the individual zones, includes, a device for scanning the tracks for recording and/or reproducing information, a device for detecting an address of a track being scanned by the recording and/or reproducing device, a device for shifting the recording and/or reproducing device from a track being scanned to another track, and a control device for determining, if an address of a desired track cannot be detected when accessing the desired track during shifting of the recording and/or reproducing device to a zone different from a zone to which the desired track belongs, and shifting, as a result, the recording and/or reproducing device to a different track.
