Abstract: Disclosed are apparatus and methods for implementing a radial sled printer device that substantially simplifies the complexity and reduces system costs and size for radial printing devices, both for devices that print and those that also record and print a label on circular media. In an embodiment, a print head is radially mounted in a substantially fixed position over a platter such that said platter moves as a sled under the print head for dispensing ink object along a radius or a line parallel to a radius as the media spins, effecting labeling of the media. In an alternate embodiment, a print head is radially mounted in a fixed position over an optical recording drive such that said drive moves as a sled under the print head for dispensing ink object along a radius as the media spins, affecting recording and labeling the media in a single insertion of the media.

Abstract: Disclosed are embodiments of an ink cartridge that includes therein a print head for dispensing ink onto a media, a movement mechanism for enabling movement of the print head, and/or an ink service station. In one embodiment, the cartridge is designed to be inserted into a receptacle so that the cartridge and receptacle form a radial printing system. The receptacle may also include a motion actuator for engaging with the movement mechanism of the cartridge to thereby move the print head of the cartridge. The movement mechanism of the cartridge works in conjunction with the actuator of the receptacle to thereby move the print head with respect to the cartridge, e.g., moving into and out of the cartridge, and with respect to a rotating media to enable ink to be dispensed by the print head along a radius of a rotating circular media. In a specific implementation, the cartridge remains fixed with respect to the media.

Abstract: Disclosed is a method for detecting an angular position of a rotating media having a native wobble signal. Prior to recording data on the rotating media, timing information is obtained from the native wobble signal in the rotating media over a substantial portion of a prerecorded media area of the rotating media. An angular position of the rotating media is determined from the timing information. The determined angular position is used to accurately print an image onto the rotating media.
