For each of the unit regions, the method of the invention determines a recording pattern corresponding to each unit region in accordance with the data related to the image to be recorded. Finally, the method of the invention controls the laser beam to irradiate a relative energy on each unit region, so as to form the corresponding recording pattern. Thereby, the whole of the recording patterns formed on the label layer exhibits the image.

Abstract: The present invention relates to a system for recording a datum onto a pixel on a light-sensitive sheet. The main component of the system is a recording unit, which further includes a light-emitting device and at least one light-guiding device. Once the light-emitting device emits a light, the light enters the light-guiding device from an entrance and is transmitted out from an exit. Before the datum is recorded, the recording unit is moved so as to align the exit of the light-guiding device with the pixel. Thereby, the light transmitted out from the exit of the light-guiding device is further projected onto the pixel to record the datum on the pixel.

Abstract: The present invention provides a system and method for recording an image onto a label layer of an optical disc. The optical disc also includes a data layer thereon that has a pregroove, in which a plurality of predetermined address codes are marked. Firstly, the system locates a first position by retrieving the predetermined address codes marked on the data layer. The system then determines a second position on the label layer in accordance with the first position. Afterward, the system records the image at the second position on the label layer by means of a laser beam or ink-jet printing. Thereby, the image is formed on the label layer of the optical disc.
