摘要： An optical pickup is opposed to an inner-radius portion of an optical disc that is set, and pits (a modulation signal) are read by applying laser light for a DVD to the inner-radius portion. The read-out modulation signal is decoded by inputting it to a CD decoder. If decoded disc information includes particular verification data, the optical disc is judged to be a legitimate optical disc of a particular type and formation of a visible image on the label surface is permitted.

摘要： When an optical disk image forming device forms an image on an optical disk, the image forming device reads information of kinds of coloring matters used in an image forming area from information described in an information area of the optical disk. Then, the optical disk image forming device reads from a table laser power strength information corresponding to the information of the kinds of the coloring matters and a maximum linear velocity (Nx) at the time of forming the image and applies a laser beam having this laser power strength to form the image on the image forming area of the optical disk. Thus, since the discoloration of the coloring matter in the image forming area is always saturated, the image having a constant contrast can be formed on the image forming area of the optical disk.

摘要： 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

摘要： An optical disk is equipped with a predetermined mark. A frequency generator outputs an FG pulse of frequency corresponding to the rotational speed of a spindle motor used for rotationally driving the optical disk. The edge of the FG pulse detected by an edge detection section is counted by an FG counter. An angle counter measures the duration of a time from appearance of an edge of the FG pulse until a point in time when the mark affixed to the optical disk 1 is detected. A count value of the FG counter, which has been acquired at the point in time when the mark is detected, and a count value of the angle counter are saved. In a case where a visible image is rendered, encoding of a visible image to be rendered is started when the count value of the FG counter and the count value of the angle counter have become equal to the respective saved values.

摘要： A relationship between a length of a pixel formed by an image drawing operation along a disk circumferential direction, and a length of a pit formed by an data recording operation along the disk circumferential direction is set in such a manner that a plurality of pits are entered to the length of 1 pixel along the disk circumferential direction. While one pixel is being drawn by employing the image drawing beam, within such a section that the power of the data recording beam becomes recording power in order to form the pit, the power of the image drawing beam is temporarily lowered to such a power which does not change the visible light characteristic of the image drawing layer.

摘要： When “buffer under run” (BUR) occurs during recording of a visible image on an optical disk, recording operation is interrupted. As in the case of type A, when BUR1 occurs after data have been transferred through an integral multiple of one revolution, data are recorded continuously from a reference angle position without host device discarding data. As in the case of type B, when BUR2 occurs after data have been transferred in a value which is other than the integral multiple of one revolution, data corresponding to a duration from the position where BUR occurs to the start of the next revolution are discarded, data are continuously recorded from the reference angle position. Thereby, rendering can be spliced in a visually-smooth manner. Further, as in the case of type C, when the volume of data remaining in a buffer has become equal to or less than a “buffer under run” threshold value, subsequent transfer of data from the host device may be interrupted, and rendering may be resumed without the host device discarding data.

摘要翻译： 当在光盘上记录可见图像期间发生“运行中的缓冲器”（BUR）时，记录操作被中断。 类似于A类的情况，当BUR1在数据已经通过一转的整数倍传送之后出现时，数据从参考角位置连续记录，而没有主机设备丢弃数据。 类似B的情况，当BUR2在数据已被传送到除了一圈的整数倍之外的值之后发生时，丢弃对应于从BUR发生的位置到下一个转的开始的持续时间的数据 从参考角位置连续地记录数据。 因此，可以以视觉平滑的方式拼接渲染。 此外，与类型C一样，当缓冲器中剩余的数据量变得等于或小于“运行中的缓冲器”阈值时，可能会中断来自主机设备的数据的后续传送，并且渲染可以 在没有主机设备丢弃数据的情况下恢复。
