Abstract
A disk-shaped sound recording medium includes a disk element with shaped outer contour with at least two contour areas which are shaped mutually complementarily to one another. At least two sound recording media can put together in the plane of the disk in the manner of a jigsaw puzzle. One of the contour areas is made curved-shaped with the disk radius (R) in the inward direction and, approximately in a center of this one of the contour areas, with an outwardly directed, undercut tongue. Another of the contour areas is provided with a groove, which is formed in a circular outer contour. The groove is shaped complementary to the tongue.
Claims19
A disk-shaped sound recording medium, comprising:
- a disk element with a center and a circular core data storage area, said disk element being provided with a shaped outer contour with a first contour area and a second contour area, said first contour area and said second contour area being shaped mutually complementarily to one another whereby at least two sound recording media are placed together in the plane of the disk in the manner of a jigsaw puzzle.
A disk-shaped sound recording medium, comprising:
- a disk element with a center and a circular core data storage area surrounding said center and with a shaped outer contour with a first contour area with a shape and having a second contour area with a shape, said second contour area being mutually complementarily to said first contour area whereby said disk element is engagable with another disk element having one of said first contour area and said second contour area for engaging complementary areas of the disk element and the another disk element in a plane of the disk element, the engagement being in the manner of a jigsaw puzzle.
A pair of data disks comprising:
- a first data disk element with a center and a circular core data storage area with a shaped outer contour with a first contour area;
- a second data disk element with a center and a circular core data storage area with a shaped outer contour with a first contour area, said first contour area of said first data disk element and said first contour area of said second data disk element being shaped mutually complementarily to one another with said first data disk element first contour area protruding relative to a complementary recess of said second data disk element first contour area, said first data disk element and said second data disk element being placed together in the plane of the first data disk element with said first contour area of said first data disk element engaged with said complementary first contour area of said second data disk element.
