Abstract

An optical storage disc label recorder includes a first memory portion adapted for storing a first set of track-marking data, the first set of track-marking data defining one or more pre-defined images, each pre-defined image having one or more pre-defined fields for dynamic text content, a second memory portion for storing a second set of track-marking data including the dynamic text content, and a digital processor adapted for combining the first and second sets of track-marking data.

Claims

1. An optical storage disc label recorder, comprising:

a) a first memory portion adapted for storing a first set of track-marking data, the first set of track-marking data defining one or more pre-defined images, each pre-defined image having one or more pre-defined fields for dynamic text content,

b) a second memory portion for storing a second set of track-marking data including the dynamic text content, and

c) a digital processor adapted for combining the first and second sets of track-marking data, whereby the dynamic text content is aligned within the one or more pre-defined fields of the one or more pre-defined images.

2. The optical storage disc label recorder of claim 1, further comprising a rendering unit coupled to the second memory portion, the rendering unit being adapted for rendering the dynamic text content to form the second set of track-marking data to be stored in the second memory portion.

3. The optical storage disc label recorder of claim 1, further comprising a keyboard adapted for entering the dynamic text content.

4. The optical storage disc label recorder of claim 1, further comprising a coupling of the second memory portion to a network for acquiring the dynamic text content and/or acquiring font-library and/or text-glyph data from a pre-determined database.

5. The optical storage disc label recorder of claim 1, further comprising a third memory portion for storing font-library and/or text-glyph data.

6. The optical storage disc label recorder of claim 1, further comprising:

optical writing apparatus to form markings on a plurality of tracks of an optically writable label side of an optical disc,

wherein the digital processor is further adapted to cause the optical writing apparatus to write the combined track marking data onto the plurality of tracks of the optical disk.

7. An optical storage disc recorder, comprising:

a) means for storing a first set of track-marking data for recording in substantially circular tracks, the first set of track-marking data defining one or more pre-defined images, each pre-defined image having one or more pre-defined fields for dynamic text content,

b) means for rendering and storing a second set of track-marking data including the dynamic text content, and

c) means for combining the first and second sets of track-marking data, whereby the dynamic text content is aligned within the one or more pre-defined fields of the one or more pre-defined images.

8. The optical storage disc recorder of claim 7, wherein the means for combining the first and second sets of track-marking data comprises means for selectively performing logical operations including logical OR and logical AND operations.

9. The optical storage disc recorder of claim 7, further comprising means for optically recording a label on at least one optical disc, the label including the pre-defined image and the dynamic text content.

10. The optical storage disc recorder of claim 9, wherein the means for optically recording comprises means for duplicating optical discs.

11. The optical storage disc recorder of claim 9, wherein the means for optically recording a label on an optical disc includes a laser.

12. In an optical storage disc recorder, a method for merging of dynamic text content with pre-determined label graphics pre-rendered in the form of first track-marking data, the method comprising:

a) storing the first track-marking data in non-volatile storage,

b) rendering the dynamic text data as second track-marking data,

c) merging the second track-marking data with selected stored first track-marking data.

13. The method of claim 12, wherein the step of merging the second track-marking data with selected stored first track-marking data is performed incrementally on a track-by-track basis.

14. The method of claim 12, wherein the first track-marking data is stored as a halftone representation.

15. The method of claim 12, wherein one or both of the first track-marking data and the second track-marking data are stored in compressed form.

16. The method of claim 12, wherein the step of merging the second track-marking data with selected stored first track-marking data comprises selectively performing logical operations including logical OR operations and/or logical AND operations.

17. The method of claim 12, wherein the step of merging the second track-marking data with selected stored first track-marking data includes defining a labeling control header associated with the merged track-marking data.

18. The method of claim 17, wherein the labeling control header associated with the merged track-marking data includes at least one parameter selected from the list consisting of:

drive type, media type, file version, file type, track start position, track curvature, inner track radius, outer track radius, starting track radius, number of tracks, track spacing, mark spacing along tracks, focus offset, laser write power, laser read power limit, spin direction, spindle speed, and combinations thereof.

19. The method of claim 12, wherein, if no pre-determined label graphics track-marking data is selected, then default first track-marking data is merged with the second track-marking data, the default first track-marking data comprising a sequence of zeros and/or ones corresponding to a white and/or black background.

20. The method of claim 12, wherein, if no dynamic text content is selected, then default second track-marking data is merged with the first track-marking data, the default second track-marking data comprising a sequence of zeros and/or ones corresponding to a white and/or black background.

21. The method of claim 12, further comprising:

d) writing onto an optical disc the merged data including second track-marking data and selected first track-marking data.
