an optical disk drive unit for driving an optical disk;

a solid-state drive (SSD) unit having a storage capacity that is equal to or greater than a maximum storage capacity of the optical disk, which is compatible with the hybrid optical disk drive; and

an interface device for connecting the optical disk drive unit and the SSD unit to an electronic system.

2. The hybrid optical disk drive of claim 1, wherein interfaces of the optical disk drive unit and the SSD unit have the same standard as each other.

3. The hybrid optical disk drive of claim 2, wherein the interface device includes a port multiplier for connecting the interfaces of the optical disk drive unit and the SSD unit to each other.

4. The hybrid optical disk drive of claim 3, wherein the interface device functions according to a serial AT attachment (SATA) standard or a universal serial bus (USB) standard.

5. The hybrid optical disk drive of claim 1, further comprising a mirroring unit for duplicating to the SSD unit optical disk data in the optical disk drive unit.

6. The hybrid optical disk drive of claim 4, wherein the SSD unit is an optical disk drive emulator which operates when the optical disk drive unit is accessed.

7. The hybrid optical disk drive of claim 1, further comprising a writing part for buffering data which will be stored in the optical disk of the optical disk drive unit to the SSD unit and writing the data buffered in the SSD unit to the optical disk drive unit.

8. An electronic system adopting the optical disk drive according to claim 1.

9. The electronic system of claim 8, wherein the SSD unit of the optical disk drive is used as a default drive for an operating system.

10. The electronic system of claim 8, wherein interfaces of the optical disk drive unit and the SSD unit have the same standard as each other.

11. The electronic system of claim 10, wherein the interface device includes a port multiplier for connecting the interfaces of the optical disk drive unit and the SSD unit to each other.

12. The electronic system of claim 8, further comprising a mirroring unit for duplicating to the SSD unit optical disk data in the optical disk drive unit.

13. The electronic system of claim 12, wherein the SSD unit is an optical disk drive emulator which operates when the optical disk drive unit is accessed.
