Image forming apparatus

Abstract

Problems that occur when printing is performed on the surface of a rotating disc by using print heads arranged in the outer circumferential direction from the center of rotation are eliminated.A light emitting section performs exposure in synchronism with rotary drive for rotating a medium, while partially superposing pixels adjoining in the circumferential direction of rotation by setting movement in the outermost circumferential direction of a medium moving between exposure intervals smaller than the circumferential width of a pixel formed by exposure. The quantity of light for exposing a pixel on the inner circumferential side in the radial direction is set smaller than that for exposing a pixel on the outer circumferential side in the radial direction at each exposure position of the medium for a plurality of light emitting sections in an optical unit. Consequently, difference in gray level due to superposition is reduced by reducing the gray scale formed by each exposure for the pixel on the inner circumferential side in the radial direction where exposure overlaps much.

Description

technical field [0001] The present invention relates to an image forming device, and more particularly to an image forming device that forms an image on a disc-shaped medium surface. Background technique [0002] Various disc-shaped media such as CD, CD-R, CD-RW, DVD, and DVD-RAM are known as recording media for recording electronic data such as images, videos, music, and documents. When writing various data on these disk-shaped media and recording, in order to be able to confirm the content recorded on this disk-shaped medium visually, information such as the title of the relevant recording content is written on the surface of the disk-shaped medium. Condition. [0003] In this case, generally, writing tools are used to directly write on the surface of the disk medium, but there are cases where the recording information is printed on separately prepared marking paper using a printer, and the marking paper is pasted on the surface of the disk medium. [0004] In this way, ...

AI Technical Summary

Problems solved by technology

Therefore, depending on the image data to be printed, the image data may not always be thinned out, so there is a problem that the overlapping of dots on the inner peripheral side cannot be completely removed.
