  • Apparatus for recording and reproducing data on a magnetic recording medium
    Patent number: 4805051
    Abstract: Apparatus for recording and reproducing data on a magnetic recording medium (27) having a plurality of recording tracks (29) comprises a magnetic head (32) and a mechanism which selectively positions the head (32) with respect to the tracks (29) of the magnetic medium (27). The head has at least two gaps which are of different widths and which can be selected one at a time for reading and/or recording data on the magnetic recording medium (27). A control circuit controls the positioning mechanism to move the head with respect to the magnetic recording medium by a distance which depends on the gap selected. The packing density of tracks on the recording medium determines which gap is selected for use.
