1. A recording and/or reproducing apparatus for recording and/or reproducing an information signal on and/or from a recording medium which is user-interchangeably loadable into said recording and/or reproducing apparatus, said recording medium having a truncated cone shape and comprising a hollow, conical part having an outer peripheral surface and opposite ends, said hollow part being open at one of said ends, and a recording surface formed on said peripheral surface of said hollow part, said hollow, conical part having only slight taper so as to be almost cylindrical, said recording and/or reproducing apparatus comprising:

  • a rotational motor including a rotary shaft and magnetic coupling means on said rotary shaft to rotatably couple said recording medium to said shaft, said motor being mounted so as to be substantially surrounded by said hollow part of said recording medium when said recording medium is loaded into said recording and/or reproducing apparatus, said magnetic coupling means supporting and magnetically coupling the other end of the loaded recording medium to the rotary shaft to allow said recording medium to be detached from the drive of said rotational motor;

    a magnetic recording and/or reproducing transducer for recording and/or reproducing an information signal on and/or from said recording surface of said recording medium with the latter rotationally driven by said magnetic coupling means of said motor; and

    feeding means for feeding said recording and/or reproducing transducer along said recording surface of said recording medium.
