Abstract

Various embodiments of the present invention are directed to a compact, portable, external optical disc drives. In one embodiment of the present invention, an optical disc drive is comprised of one or more substrates having a width smaller than the diameter of an optical disc and that covers and protects one or more data recording surfaces of the optical disc. The optical disc drive may also include an external connector that is capable of plugging into an outlet of an electrical device so that the optical disc drive extends beyond an external sidewall of the electrical device and is electronically interconnected to the electrical device.

Claims

1. An optical disc drive comprising:

a substrate having a width smaller than the diameter of an optical disc;

a clamping mechanism supported by the substrate for receiving the optical disc;

one or more guides connected to the substrate;

an optical assembly supported by the guides and being moveable along the guides in a radial direction of the optical disc; and

an external connector that provides electrical connections between the substrate and an electrical device and is capable of plugging into an outlet of the electrical device so that the optical disc drive extends beyond an external sidewall of the electrical device.

2. The optical disc drive of claim 1 further comprising:

one or more motors that rotate the clamping mechanism and optical disc together;

a motor connected to the optical assembly that includes a gear with teeth; and

a rack fixed to the substrate, the rack having teeth that interlock with the teeth of the gear so that the optical assembly can be moved along the guide surfaces in the radial direction of the optical disc as a result of rotation of the gear.

3. The optical disc drive of claim 2 wherein the substrate further comprises electrical interconnections that interconnect the motors that rotate the clamping mechanism, the optical assembly, and the external connector.

4. The optical disc drive of claim 2 wherein the rack is fixed to either the substrate or one or more of the gears.

5. The optical disc drive of claim 1 further comprising a cover and a flap that protects the optical assembly and substrate.

6. The optical disc drive of claim 1 wherein the guides are cylindrical guides connected to supports and the external connector.

7. The optical disc drive of claim 1 wherein the guides include slots that span the length of each guide.

8. The optical disc drive of claim 1 wherein the optical assembly further comprises one or more light sources, an optical lens, and a sensor for detecting light reflected from a data recording surface of the optical disc.

9. The optical disc drive of claim 1 further comprising an optical disc cover.

10. The optical disc drive of claim 9 wherein the optical disc cover further comprises a number of interlocking vanes.

11. The optical disc drive of claim 9 wherein the optical disc cover further comprises a single piece of material that can be folded and unfolded.

12. The optical disc drive of claim 1 wherein the external connector includes a rotatable interface with the substrate so that the external connector can be rotated.

13. An expandable optical disc drive comprising:

a first substrate and a second substrate, each having a width smaller than the diameter of an optical disc;

a clamping mechanism supported by the first substrate for receiving the optical disc;

one or more guides connected to the first substrate;

one or more guides connected to the second substrate, each being moveable along the guides of the first substrate so that the second substrate can slide over the first substrate;

an optical assembly being moveable along the guides of the second substrate in a radial direction of the optical disc; and

an external connector that is capable of plugging into an outlet of an electrical device so that the optical disc drive extends beyond an external sidewall of the electrical device and is electronically interconnected to the electrical device.

14. The optical disc drive of claim 13 further comprising:

one or more motors connected to the first substrate that rotate the clamping mechanism and optical disc together;

a motor connected to the optical assembly that includes a gear with teeth; and

a rack having teeth that interlock with the teeth of the gear so that the optical assembly can be moved along the guide of the second substrate in the radial direction of the optical disc.

15. The optical disc drive of claim 14 wherein the first and second substrates further comprise electrical interconnections that interconnect the motors that rotate the clamping mechanism, the optical assembly, and the external connector.

16. The optical disc drive of claim 14 wherein the rack is fixed to either the substrate or one or more of the gears.

17. The optical disc drive of claim 13 wherein the guides include slots that span the length of each guide.

18. The optical disc drive of claim 13 wherein the optical assembly further comprises one or more light sources, an optical lens, and a sensor for detecting light reflected from a data recording surface of the optical disc.
