Abstract
Methods and apparatus for interleaved printing of individual ink objects at target print sectors disbursed around an annular surface on a circular spinning media such as on a CD, dynamically during the radial printing process, are described. Mechanisms for interleaving printing during the radial printing process, enabling the use of commercially available ink jet pens for radial printing directly on CD devices at greater than 2× rotation speeds, and thus reducing pen limitations in firing frequency and recovery time, are disclosed.

A method of printing onto a rotating media, comprising:
- rotating the media at a selected rotation speed, the media having a radial print track that is subdivided into a plurality of sectors such that the plurality of sectors have a same radius, each sector comprising an annular portion of the radial print track;
- dispensing ink onto a first sector of the plurality of sectors during a first rotation of the media;
- and
- dispensing ink onto a second sector of the plurality of sectors during a second rotation of the media, wherein the radial print track has a larger area than either the first sector or the second sector and wherein the second rotation of the media occurs within any one of subsequent successive rotations after the first rotation of the media.

A method of printing onto a rotating media, comprising:
- rotating the media at a selected rotation speed;
- dispensing ink onto a first sector of a radial print track of the rotating media during a first rotation of the media, the radial print track having a corresponding radius;
- and
- dispensing ink onto a second sector of the radial print track of the rotating media during a second rotation of the media, wherein the radial print track has a larger area than either the first sector or the second sector and wherein the second rotation of the media occurs within any one of subsequent successive rotations after the first rotation of the media,
- wherein the rotation speed is selected so that ink is dispensed onto a first sub-sector and not onto a second sub-sector of the first sector during the first rotation, the method further comprising dispensing ink onto the second sub-sector of the first sector during the second rotation, the first sub-sector of the first sector being contiguous with the second sub-sector of the first sector.

A printing system for radially printing onto a rotating media, comprising:
- a rotation mechanism for rotating the media at a selected rotation speed, the media having a radial print track that is subdivided into a plurality of sectors such that the plurality of sectors have a same radius, each sector comprising an annular portion of the radial print track;
- a dispensement mechanism for dispensing ink onto the media while the media is rotating under the dispensement mechanism;
- and
- a controller for causing the dispensement mechanism to:

- and
- dispense ink onto a second sector of the plurality of sectors during a second rotation of the media, wherein the radial print track has a larger area than either the first sector or the second sector and wherein the second rotation of the media occurs within any one of subsequent successive rotations after the first rotation of the media.
