摘要： A method of accessing recording and/or reproducing means to a desired track of an information recording medium having a plurality of parallel tracks, wherein said recording and/or reproducing means and the recording medium are not relatively moved in a longitudinal direction of the tracks while the recording and/or reproducing means is moved relative to recording medium in a direction so as to cross the tracks. An apparatus for recording and/or reproducing information, comprises:
means for recording information in and/or reproducing the information from a recording having a plurality of parallel tracks;
first driving means for moving the recording medium relative to said recording and/or reproducing means in a longitudinal direction of the tracks;
second driving means for moving said recording and/or reproducing means relative to the recording medium in a direction so as to cross the tracks; and
means for controlling to disable the first driving means when the second driving means is operated.
