Abstract

An optical disk changer that is capable of automatically playing both sides of a dual-sided optical disk. By coordinated delivery of disks between a disk reader, a disk transfer mechanism, or a disk turner and a carrousel that is approximately toroid shaped, both sides of a dual-sided optical disk can be automatically accessed.

Claims

1. An optical disk changer for reading a first and a second side of an optical disk comprising:

a base;

a carrousel rotationally coupled to the base, the carrousel being configured to hold a plurality of dual-sided optical disks;

an optical disk reader centrally disposed with respect to the carrousel;

a bidirectional first loading mechanism carried adjacent a first side of the optical disk reader, the first loading mechanism being adapted to translate a disk in a first direction from the carrousel into the first side of the disk reader and to translate a disk in a second direction from the disk reader onto the carrousel;

a bidirectional second loading mechanism carried adjacent a second side of the optical disk reader, the second loading mechanism being adapted to translate a disk in the second direction from the carrousel into the second side of the disk reader and to translate a disk in the first direction from the disk reader onto the carrousel;

the first and second loading mechanisms being adapted to cooperate to transfer a single optical disk along a straight path from the carrousel into the first side of the disk reader, and out of the second side of the disk reader back onto the carrousel.

2. The optical disk changer of claim 1 wherein the carrousel is free to rotate while an optical disk is being read with the optical disk reader.

3. The optical disk changer of claim 1 wherein the carrousel includes a plurality of disk-receiving slots and the carrousel is free to rotate after the optical disk is transferred into the disk reader from a first one of the slots to position the first slot adjacent the second side of the disk reader to receive the optical disk in the first slot from the second loading mechanism.

4. The optical disk changer of claim 1 wherein said carrousel holds disks radially about a center rotation point of said carrousel with the rotational axis of each optical disk substantially perpendicular to the axis of rotation of the carrousel.

5. The optical disk changer of claim 4 wherein said carrousel has slots for holding the plurality of optical disks.

6. The optical disk changer of claim 1 wherein the first loading mechanism includes two substantially parallel cylinders that cooperatively rotate to move the optical disk with respect to the optical disk reader and the second loading mechanism includes two substantially parallel cylinders that cooperatively rotate to move the optical disk with respect to the optical disk reader.

7. The optical disk changer of claim 1 further comprising a first ejector arm for pushing the optical disk from said carrousel along a first direction.

8. The optical disk changer of claim 7 further comprising a second ejector arm for pushing the optical disk from said carrousel along a direction opposite to the first direction.

9. The optical disk changer of claim 1 wherein the carrousel is adapted to rotate about a vertical axis.

10. The optical disk changer of claim 1 wherein the second direction is opposite to the first direction.

11. The optical disk changer of claim 1 wherein the carousel is horizontally oriented and adapted for rotation about a vertical axis.

12. An optical disk changer for reading a first and a second side of an optical disk comprising:

a base;

a carrousel means rotationally coupled to the base, the carrousel means being configured to hold a plurality of dual-sided optical disks;

an optical disk reader means centrally disposed with respect to the carrousel means;

a bidirectional first loading means, carried adjacent a first side of the optical disk reader means, for translating a disk in a first direction from the carrousel means into the first side of the disk reader means and for translating a disk in a second direction from the disk reader means onto the carrousel means;

a bidirectional second loading means, carried adjacent a second side of the optical disk reader means, for translating a disk in the second direction from the carrousel means into the second side of the disk reader means and for translating a disk in the first direction from the disk reader means onto the carrousel means;

the first and second loading means being adapted to cooperate to transfer a single optical disk along a straight path from the carrousel means into the first side of the disk reader means, and out of the second side of the disk reader means back onto the carrousel means.

13. The optical disk changer of claim 12 wherein the carrousel means is free to rotate while an optical disk is being read with the optical disk reader means.

14. The optical disk changer of claim 12 wherein the carrousel means includes a plurality of disk-receiving slot means and the carrousel means is free to rotate after the optical disk is transferred into the disk reader means from a first one of the slot means to position the first slot means adjacent the second side of the disk reader means to receive the optical disk in the first slot means from the second loading means.

15. The optical disk changer of claim 12 wherein said carrousel means holds disks radially about a center rotation point of said carrousel means with the rotational axis of each optical disk substantially perpendicular to the axis of rotation of the carrousel means.

16. The optical disk changer of claim 15 wherein said carrousel means has slots for holding the plurality of optical disks.

17. The optical disk changer of claim 12 wherein the first loading means includes two substantially parallel cylinders that cooperatively rotate to move the optical disk with respect to the optical disk reader means and the second loading means includes two substantially parallel cylinders that cooperatively rotate to move the optical disk with respect to the optical disk reader means.

18. The optical disk changer of claim 12 further comprising a first ejector means for pushing the optical disk from said carrousel means along a first direction.

19. The optical disk changer of claim 18 further comprising a second ejector means for pushing the optical disk from said carrousel means along a direction opposite to the first direction.
