Abstract

Provided are a hybrid optical disk drive, a method of driving the hybrid optical disk drive, and an electronic system including the hybrid optical disk drive. The hybrid optical disk drive may include an optical disk drive unit for recording/storing data in an optical disk and 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.

Claims

1. A hybrid optical disk drive comprising:

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, and which is compatible with the hybrid optical disk drive;

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

at least one of a mirroring unit configured to duplicate to the SSD unit optical disk data in the optical disk drive unit or a writing art configured to buffer data which will be stored in the optical disk to the SSD unit.

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 configured to connect 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, wherein the at least one of the mirroring unit or the writing part is the mirroring unit, and the mirroring unit is configured to duplicate 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, wherein the at least one of the mirroring unit or the writing part is the writing part, and the writing part is configured to buffer 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 comprising the hybrid optical disk drive according to claim 1.

9. The electronic system of claim 8, wherein the SSD unit of the hybrid 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 configured to connect the interfaces of the optical disk drive unit and the SSD unit to each other.

12. The electronic system of claim 8, wherein the at least one of the mirroring unit or the writing part is the mirroring unit, and the mirroring unit is configured to duplicate 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.

14. The electronic system of claim 8, wherein the at least one of the mirroring unit or the writing part is the writing part, and the writing part is configured to buffer 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.

15. A method of driving a hybrid optical disk drive comprising an optical disk drive unit and a solid-state drive (SSD) unit to be connected to an electronic system, the method comprising:

duplicating data of an optical disk inserted in the optical disk drive unit to the SSD unit; and

reproducing the data duplicated in the SSD unit according to a data reproducing command of the optical disk.

16. The method of driving a hybrid optical disk drive of claim 15, further comprising:

substituting a general hard disk drive with the hybrid optical disk drive, wherein the SSD unit is configured to act as a hard disk drive emulator.

17. A method of driving a hybrid optical disk drive comprising an optical disk drive unit and a solid-state drive (SSD) unit to be connected to an electronic system, the method comprising:

duplicating the data from the electronic system to the SSD unit; and
