Abstract

A method and apparatus for accessing a track in a recording medium during a stopped state of recording or reproduction. The method includes accessing a recording and/or reproducing device to a desired track of a plurality of tracks on the information recording medium. The recording and/or reproducing device and the recording medium are not relatively moved in a longitudinal direction of the tracks, while the recording and/or reproducing device is moved relative to the recording medium in a direction which crosses the tracks. The apparatus for recording and/or reproducing information includes a device for recording information on and/or reproducing information from a recording medium having a plurality of parallel tracks, a first driving device for moving the recording medium relative to the recording and/or reproducing device in a longitudinal direction of the tracks, a second driving device for moving the recording and/or reproducing device relative to the recording medium in a direction crossing the tracks, and a device for controlling the first driving device for disabling the first driving device when the second driving device is operated.
