Abstract

The present disclosure provides apparatus and methods for reading optical disks. Some implementations are particularly well suited for 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. A method of translating an optical disk comprising:

(a) translating the optical disk from a carrousel to a disk reader along a first direction by delivering the optical disk from the carrousel to a first loading mechanism at a first side of the disk reader, the first loading mechanism driving the disk into the disk reader with a first side of the oitical disk in a first orientation with respect to the disk reader; and

(b) with the first side of the optical disk in the first orientation with respect to the disk reader, translating the optical disk from the disk reader to the carrousel along the first direction with a second loading mechanism at a second side of the disk reader.

2. The method of claim 1 further comprising translating the optical disk from the carrousel to the disk reader along the first direction with the first loading mechanism, wherein the optical disk is in a second orientation with respect to the disk reader and the second orientation is different from the first orientation.

3. The method of claim 2 further comprising rotating the carrousel after translating the optical disk in the first orientation from the disk reader to the carrousel and before translating the optical disk in the second orientation from the carrousel to the disk reader.

4. A method of reading data from an optical disk comprising:

(a) holding the optical disk in a carrousel;

(b) delivering the optical disk from the carrousel to a first loading mechanism at a first side of a disk reader;

(c) driving the optical disk in a first direction with the first loading mechanism to a location within the carrousel with a first side of the optical disk in a first orientation with respect to the disk reader;

(d) reading data from the first side of the optical disk;

(e) with the first side of the optical disk in the first orientation with respect to the disk reader, delivering the optical disk from the location to the carrousel by driving the optical disk in the first direction with a second loading mechanism at a second side of the disk reader;

(f) rotating the carrousel;

(g) delivering the optical disk from the carrousel to the first loading mechanism at the first side of the disk reader;

(h) driving the optical disk in the first direction with the first loading mechanism to the location within the carrousel with a first side of the optical disk in a second orientation, which differs from the first orientation, with respect to the disk reader; and

(i) reading data from a second side of the optical disk.

5. The method of claim 4 wherein rotating the carrousel comprises rotating the carrousel about a vertical axis.

6. A method of translating an optical disk having a first side and a second side comprising:

(a) holding the optical disk in a carrousel;

(b) if data from the first side of the optical disk is to be read, then translating the optical disk to a reading location within the carrousel in a first direction via a first loading mechanism on a first side of a disk reader; and

(c) if data from the second side of the optical disk is to be read, then translating the optical disk to the same reading location in a direction opposite to the first direction via a second loading mechanism on a second side of the disk reader.

7. A method of translating an optical disk comprising:

holding a dual-sided optical disk in a carrousel;

positioning the optical disk adjacent a first side of a disk reader;

driving the optical disk into the disk reader via a first loading mechanism adjacent the first side of the disk reader;

reading the first side of the optical disk with the disk reader with the first side in a first orientation with respect to the disk reader; and

with the first side in the first orientation with respect to the disk reader, driving the optical disk out of the disk reader via a second loading mechanism adjacent a second side of the disk reader and receiving the optical disk in the carrousel.

8. The method of claim 7 wherein the first loading mechanism and the second loading mechanism drive the optical disk in the same direction.

9. The method of claim 7 wherein the carrousel has a plurality of slots, the optical disk being held in a first one of the slots.

10. The method of claim 9 further comprising rotating the carrousel after driving the optical disk into the disk reader to position the carrousel to receive the optical disk from the disk reader in the first slot.

11. The method of claim 7 wherein the carrousel is rotationally coupled to a base and the disk reader is positioned within the carrousel, the carrousel receiving the optical disk from the second loading mechanism at a location diametrically opposite the location where the disk is positioned adjacent the first side of the disk reader.

12. The method of claim 7 further comprising, after receiving the optical disk in the carrousel from the second loading mechanism:

rotating the carrousel to position the optical disk adjacent the first side of the disk reader;

driving the optical disk into the disk reader via the first loading mechanism; and

reading the second side of the optical disk with the disk reader.

13. The method of claim 7 further comprising, after receiving the optical disk in the carrousel from the second loading mechanism:

rotating the carrousel to position the optical disk adjacent the first side of the disk reader;

driving the optical disk into the disk reader via the first loading mechanism; and

reading the second side of the optical disk with the disk reader with the first side in a second orientation, which differs from the first orientation, with respect to the disk reader.

14. A method of translating an optical disk comprising:

holding a dual-sided optical disk in a carrousel, the optical disk having a first side and a second side;

determining whether the first side or the second side of the disk is to be read; and

if the first side of the optical disk is to be read;

positioning the optical disk adjacent a first side of a disk reader;

driving the optical disk in a first direction to a reading location within the disk reader via a first loading mechanism at the first side of the disk reader; and

reading the first side of the optical disk with the disk reader;

or

if the second side of the optical disk is to be read;

positioning the optical disk adjacent a second side of the disk reader;

driving the optical disk in a second direction to the same reading location within the disk reader via a second loading mechanism at the second side of the disk reader, the second direction being opposite the first direction; and

reading the second side of the optical disk with the disk reader.
