Method and apparatus for printing onto a rotating media is described. According to one embodiment, the printing system includes a print head that is laterally displaced from a radial printing radius, a rotating mechanism to rotate the media, and a controller to print onto an annular print area. The annular print area is defined by an inner hub circumference, two lines substantially parallel to the radial printing radius and tangential to the inner hub circumference, and an outer edge of the media. The print head moves about the annular print area by one or more motion mechanism and prints images onto the media.

Off-radial-axis circular printing device and methods

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&#xd7; rotation speeds, and thus reducing pen limitations in firing frequency and recovery time, are disclosed.
