Abstract
An apparatus for recording and/or reproducing a disc-shaped recording medium, such as an optical disc, includes first and second recording and/or reproducing units and a supporting member. The first and second recording and/or reproducing units record and/or reproduce the discs and are mounted in a layered fashion parallel to each other on the supporting member. One of the first and second recording and/or reproducing units is arranged on one surface of the supporting member, while the other recording and/or reproducing unit is arranged on the opposite surface of the supporting member.
Claims14
A disc recording and/or reproducing apparatus comprising:
- first recording and/or reproducing means for recording and/or reproducing a first disc having a scanning surface, said first recording and/or reproducing means including first rotational driving means for rotationally driving the first disc and first head means for recording and/or reproducing data on the first disc;
- second recording and/or reproducing means for recording and/or reproducing a second disc having a scanning surface, said second recording and/or reproducing means including second rotational driving means for rotationally driving the second disc and second head means for recording and/or reproducing data on the second disc;
- and
- supporting means for supporting said first recording and/or reproducing means and said second recording and/or reproducing means in a layered state, said supporting means carrying said first recording and/or reproducing means on a first surface side thereof and also carrying said second recording and/or reproducing means on, a second surface side thereof which faces away from said first surface side,
- wherein said first recording and/or reproducing means and said second recording and/or reproducing means are arranged on said supporting means such that the first and second discs, which are rotationally driven by said first rotational driving means and said second rotational driving means, respectively, each rotate in a plane substantially parallel to each other, and
- wherein said first rotational driving means and said second rotational driving means are arranged on said first recording and/or reproducing means and said second recording and/or reproducing means, respectively, so that one of said first rotational driving means and said second rotational driving means is offset relative to the other of said first rotational driving means and said second rotational driving means such that the first and second rotational driving means have different rotational axes.

A disc recording and/or reproducing apparatus comprising:
- first recording and/or reproducing means for recording and/or reproducing a first disc, said first recording and/or reproducing means including first rotational driving means for rotationally driving the first disc and first head means for recording and/or reproducing data on the first disc;
- second recording and/or reproducing means for recording and/or reproducing a second disc, said second recording and/or reproducing means including second rotational driving means for rotationally driving the second disc and second head means for recording and/or reproducing data on the second disc;
- and
- supporting means for supporting said first and second recording and/or reproducing means, said supporting means supporting said first and second recording and/or reproducing means in the recording and/or reproducing state of the first and second discs such that the first and second discs are substantially parallel to each other,
- wherein said second recording and/or reproducing means is layered with respect to said first recording and/or reproducing means with said supporting means placed solely in between the first and second discs, and
- wherein said first rotational driving means and said second rotational driving means are respectively arranged on said first recording and/or reproducing means and said second recording and/or reproducing means so that one of said first rotational driving means and said second rotational driving means is offset relative to the other of said first rotational driving means and said second rotational driving means such that the first and second rotational driving means have different rotational axes.
