This difference in reflectance makes it possible to visualize the area irradiated with the laser light 2. However, since the visible region is small in this case, in order to draw a necessary pattern, it is necessary to arrange a large number of pits 9 like a mosaic as shown in FIG. When the pulse width is increased (the time per pulse is increased), the pit length is also increased. Therefore, information for designating the pulse width is added to the visible-only data sent from the label creating means 37, and a plurality of pulse widths are selected.

FIG. 4 is a sectional view of laser light emitted from the CD-RW medium and the optical pickup according to the second embodiment of the present invention. FIG. 5 is a CD-RW medium view seen from the data side after data formation in the second embodiment of the present invention, and FIG. 6 is a partially enlarged view of the CD-RW medium of FIG. Embodiment 2
The optical disk device of is basically the same as the optical disk device of the first embodiment except that the optical disk is a CD-RW, and FIG. 9 is also referred to in the second embodiment.

In FIG. 4, 10 is a CD-RW medium, 1
Reference numeral 1 is a laser beam emitted from the optical pickup 25 (see FIG. 9). Two types of laser light 11 are used: a wavelength near 830 nm used for recording and a wavelength near 780 nm. The layer structure of the CD-RW medium 10 will be described. As shown in FIG. 4, in the CD-R medium 10 of the second embodiment, 12 is the CD-RW medium 10.

A recording layer for recording data by utilizing the existence of two phases, an amorphous state phase (non-crystalline state phase), and 18 for protecting the recording layer 16 and laser light 1
1 is a transparent layer composed of a substrate of polycarbonate, acrylic resin or the like that transmits 1. After recording with the laser beam 11, the portion in the amorphous state phase has a low reflectance and can be read like a pit, and a signal equivalent to a CD-ROM can be obtained. Reference numeral 19 is a wobbled groove that is meandered (wobbled) in a sinusoidal shape to form a track when writing to the CD-RW medium 10.

Since the operation of reproducing data from or reproducing data from the CD-RW medium 11 using the optical disk device shown in FIG. 9 is the same as that of the first embodiment, it is omitted here. The operation of the optical disk device when creating a label will be described.

The optical disk device is ATAPI / SCSI.
When the label producing data is received from the label producing means 37 through the interface 31, the buffer manager 29 temporarily stores the data in the buffer RAM 30. The write start point is determined by extracting the ATIP information of the wobble signal by the ATIP decoder 33. The label creating means 37 can appropriately set the pulse width of the pulse for operating the laser control circuit 36,
The visible-only data stored in the memory is read out, and the laser control circuit 36 is used as label creation data together with other data.
Or to the motor driver 23 to adjust the intensity of the laser beam 11 to visualize the recording layer 16. The label creation data includes visible-only data for forming patterns and the like, which are written on the label and optically recorded, in pits. The visible-only data causes a visible physical change by the laser beam 11 and is formed as a large number of pits, and a pattern or the like is drawn as an aggregate of these pits.

That is, first, the laser light 11 is focused on the wobble groove 19, and the laser light 11 causes a phase change in the recording layer 16. As described above, this phase change film becomes an amorphous state phase by rapid heating and rapid cooling by the laser light 11, and gradually becomes a crystalline state phase by gradually heating and gradually cooling (slow heating, slow cooling).

Since the recording layer 16 has a high reflectance in the crystalline state phase after cooling and has a low reflectance in the amorphous state phase, the difference in the reflectance of this crystal structure (visible physical change).
This makes it possible to visualize the region irradiated with the laser light 11. However, since the visible area is small in this case, in order to draw a necessary pattern, it is necessary to arrange a large number of pits 20 like a mosaic as shown in FIG. When the pulse width is increased (the time per pulse is increased), the pit length is also increased. Therefore, information for designating the pulse width is added to the visible-only data sent from the label creating means 37, and a plurality of pulse widths are selected. If it can be used, it is possible to specify a design with the pits 20 having a plurality of shapes. In other words, the label creating means 37 can create a label with a plurality of types of pits 20,
By combining these several kinds of pits 20, it is possible to make the design as natural as possible, and it is possible to form optical recording of any design on the recording layer 16 of the CD-RW medium 10.

The CD-RW medium 1 thus created
When 0 is generally viewed, as shown in FIG. 5, for example, the label "only this disc is **" for visible data can be read. The details of the visible-only data at this time are as shown in FIG. 6. For example, “D” is composed of a large number of pits 20 collected as an aggregate.

For example, FIG. 7 shows a business card size disc. To visualize this optical disc,
If this optical disk is the CD-R medium 1, the first embodiment
Visualization should be performed with the optical disc device of CD-RW.
In the case of the medium 10, visualization may be performed by the optical disk device according to the second embodiment. Visualization may be similarly performed on other optical disk media. Details are omitted here.

By the way, in the case of the optical disk device of the third embodiment, as shown in FIG. 7, it is possible to set the write position of the label to the circular data outside area, but the ATIP of the wobbled grooves 8 and 19 of the data area is possible. (Absolute Ti
me In Pregroove) cannot be used simply. Therefore, in the case of the third embodiment, it is necessary to form a wobble groove for forming the visible-only data even in the circular area outside the data. Then, any other means may be used as long as it is a means for specifying the position where the laser light is irradiated. As shown in FIG. 8, the visualization-dedicated data is also written in the non-data area by the optical disk device that records and reproduces the data for data recording in the data area, and a large number of pits 21 are formed.
