Abstract

A virtual jukebox providing access to data content of a removable medium, such as a compact disc or digital versatile disc. In one embodiment, the jukebox includes a removable media drive, as well as a hard disk drive in communication with the removable media and a host. The removable media drive stores to the hard disk drive the data contents of a removable medium loaded into the removable media drive. The hard disk drive provides the host access to the data content stored on the hard disk drive by way of a logical view of a virtual removable media drive loaded with the removable medium. The virtual jukebox may be coupled with the host by way of the host system bus, or a network coupled with the host. In an alternative embodiment, the virtual jukebox is implemented as a standalone unit.

Claims

1. A virtual multiple removable media jukebox, comprising:

a host;

a removable media drive in communication with the host;

a hard disk drive in communication with the removable media drive and the host, the hard disk drive storing a datum received from the removable media drive;

a driver operative to provide access for the host to the datum stored on the hard disk drive by presenting to the host a logical view of a virtual removable media drive loaded with the datum;

wherein the removable media drive is configured to store to the hard disk drive the data contents of a removable medium loaded into the removable media drive.

2. The virtual multiple removable media jukebox of claim 1, wherein the hard disk drive communicates with the host by way of a device controller coupled with a system bus of the host.

3. The virtual multiple removable media jukebox of claim 1, wherein the hard disk drive communicates with the host by way of a network.

4. The virtual multiple removable media jukebox of claim 1, wherein the data content of each removable medium loaded into the removable media drive is stored in a mutually exclusive group of sectors of the hard disk drive.

5. The virtual multiple removable media jukebox of claim 4, wherein each mutually exclusive group of sectors is contiguous.

6. The virtual multiple removable media jukebox of claim 1, wherein the removable medium is chosen from the group comprising:

a compact disc and a digital versatile disc.

7. The virtual multiple removable media jukebox of claim 1, further comprising a data compressor configured to compress the data content from the removable medium loaded in the removable media drive prior to storing the data content on the hard disk drive.

8. A host, comprising:

a processor;

a removable media drive; and

a hard disk drive in communication with the removable media drive and in communication with the processor;

wherein the removable media drive is configured to store to the hard disk drive the data contents of a removable medium loaded into the removable media drive; and

wherein the hard disk drive provides access by the processor to the data contents stored on the hard disk drive from the removable medium by presenting to the processor a logical view of a virtual removable media drive loaded with the removable medium.

9. The host of claim 8, further comprising a device driver executable on the processor, the device driver configured to translate commands received from a file system of the host intended for a virtual removable media drive to the hard disk drive.

10. The host of claim 8, further comprising a device controller in communication with the hard disk drive and the processor, the device controller configured to map commands from the processor to commands associated with a disk-related interface.

11. The host of claim 8, wherein the removable medium comprises a compact disc.

12. The host of claim 8, the host further comprising:

a first enclosure encompassing the processor; and

a second enclosure encompassing the removable media drive and the hard disk drive.

13. A networked system, comprising:

at least one host;

a network coupled with the at least one host;

a removable media drive; and

a hard disk drive in communication with the removable media drive and in communication with the network;

wherein the removable media drive is configured to store to the hard disk drive the data contents of a removable medium loaded into the removable media drive; and

wherein the hard disk drive provides access by the at least one host to the data contents stored on the hard disk drive from the removable medium by presenting to the at least one host a logical view of a virtual removable media drive loaded with the removable medium.

14. The networked system of claim 13, the host comprising:

a processor; and

a device driver executable on the processor, the device driver configured to translate commands received from a file system of the host intended for a virtual removable media drive to the hard disk drive.

15. The networked system of claim 13, wherein communication between the at least one host and the hard disk drive is asynchronous.

16. The virtual multiple removable media jukebox of claim 13, wherein the removable medium is chosen from the group comprising:

a compact disc and a digital versatile disc.

17. The virtual multiple removable media jukebox of claim 16, further comprising a data compressor configured to compress the data content from the removable medium loaded in the removable media drive prior to storing the data content on the hard disk drive.

18. A standalone virtual multiple removable media jukebox, comprising:

a user interface;

a removable media drive;

a hard disk drive in communication with the removable media drive and in communication with the device controller;

wherein the removable media drive is configured to store to the hard disk drive the data contents of a removable medium loaded into the removable media drive; and

wherein the hard disk drive provides access by the user interface to the data contents stored on the hard disk drive from the removable medium by presenting to the user interface a logical view of a virtual removable media drive loaded with the removable medium.

19. The standalone virtual multiple removable media jukebox of claim 18, further comprising a device controller in communication with the user interface and the hard disk drive, the device controller mapping commands originating from the user interface to a disk-related interface employed by the hard disk drive.

20. The standalone virtual multiple removable media jukebox of claim 19, further comprising a combined device driver and user interface logic in communication with the user interface and the device controller, the combined device driver and user interface logic configured to translate commands from the user interface into a form understandable by the device controller.

21. The standalone virtual multiple removable media jukebox of claim 18, the user interface comprising a user input device selected from the group consisting of a touch pad, a keypad, a touch screen, and a remote control.

22. The standalone virtual multiple removable media jukebox of claim 20, further comprising an audio device coupled with the combined device driver and user interface logic, the audio device being configured to reproduce audio content represented by the data content stored on the hard disk drive.

23. A method for providing content of a removable media, comprising:

reading data content of a removable medium;

storing a copy of the data content from the removable medium on a hard disk drive; and

upon request for access to the data content of the removable medium, providing access to the copy of the data content stored on the hard disk drive by way of a logical view of the data content as stored on the removable medium.

24. The method of claim 23, wherein the access to the data content allowed by the providing step is read access.

25. The method of claim 23, wherein the access to the data content allowed by the providing step is write access.

26. The method of claim 23, further comprising compressing the copy of the data content stored on the hard disk drive in comparison to the data content of the removable medium.

27. The method of claim 23, wherein the copy of the data content is accessed in the access providing step by a host via a system bus of the host.

28. The method of claim 23, wherein the copy of the data content is accessed in the access providing step by a host via a network.
