Abstract
An optical disk has inner and outer information areas respectively in inner and outer portions thereof in each of which a groove is formed at a predetermined width. A planar mirror surface is provided without forming a groove, in an area lying between the areas. When a laser beam is applied to the area to form a visible image, visible-image information, capable of representing the position, shape and size of an area occupied by the visible image, is formed and recorded in the area. When additionally forming a visible image, the image area information is read from the area to display on an edit screen an optical disk and an area of a visible image already formed on the surface of the disk. The user is allowed to determine a newly-recording visible image and its position by use of the edit screen.
