The present invention relates to a label forming method on an optical disc, and more particularly, to record a picture or a photo on a part of an optical disc multilayer recording surface so that visual information, not data, can be viewed without using a label printer. The present invention relates to a method for forming a label suitable for leaving information on the disc and the content to be recorded on a recording surface.

In general, a DVD disc can store seven times the size of a CD in the same size as a CD 12 cm in diameter and 1.2 mm thick. In addition, the DVD disc is a storage medium that can store up to 17GB, depending on whether the playback surface is single-sided, double-sided, or single or double layers.

Conventionally, optical recording media including CDs or DVDs have been used in the form of memo using writing instruments on the surface of the disc for recording and storing the data, or by attaching printed paper on the opposite side of the recording surface.

However, such a method is cumbersome, there is a concern that the recording may be discolored or fall off over time, and there has been a problem of damaging the appearance of the disc itself.

As a method for improving the problem, there have been methods of drawing on the recordable area after recording on the recording surface or by using a laser after applying a photosensitive material on the label surface.

FIG. 1 shows a form in which a picture is drawn in a remaining recordable area after data is recorded on a conventional recording surface.

However, according to the above method, since data can be drawn only in the remaining recordable area after data is recorded on the recording surface, there is a problem that a large limit is placed on the capacity for drawing according to the amount of data.

2 shows a form in which a picture is drawn using a laser after the photosensitive material is coated on a label surface.

However, according to the above method, since the recording is performed after the photosensitive material is coated on the label surface, the recording time is too long, and there is a problem that the drawing cannot be restored when the focus drops due to the vibration during recording.

The present invention has been proposed to solve the problems of the prior art as described above,

It is an object of the present invention to provide a method for forming a label on a recording surface on an optical disk stably without being influenced by the capacity of data to be recorded on the recording surface and without the influence of vibration in a short time.

The present invention includes the steps of determining the type of optical recording medium; Editing and encoding a label to be recorded on a partial layer of the optical disc having a multilayer recording surface; And modulating the encoded image to form a label by turning on / off a laser according to a pattern on a recording layer different from the recording layer on which data is recorded.

According to the present invention, there is provided a method of forming a label in an optical disc, wherein the label is formed to have a space after a predetermined time for power control of the laser used to form the label.

According to the present invention, the label provides a method for forming a label on an optical disc, characterized in that it comprises a picture, a picture or a letter.

Hereinafter, the content of the present invention will be described in detail with reference to the accompanying drawings.

 Figure 3 shows a plan view (a) and a cross sectional view (b) in a state where a label is formed on a part of the recording surface according to the present invention.

An optical disc that can be used in the present invention has a multi-layer recording surface. In the case of having a multi-layer recording surface, a partial layer may be used as an area for recording an image for label formation.

Since the recording layers each have a different recording film color, when appropriately used, the recording layers can be given color by selecting the color of the image to be recorded.

In FIG. 3B, although the label layer is formed on the upper layer and the data recording layer is located on the lower layer, it is not necessarily limited thereto. Therefore, it is also possible to make the label layer the lower layer and the data recording layer the upper layer.

 When a program that supports an image transfers a pattern of the image to the optical disc recording drive, the optical drive turns on the laser that matches the pattern of the image while the focus / tracking servo is engaged to form the image after the optical pickup jumps. The label can be formed on / off.

Fig. 4 shows a pattern diagram of the recording laser used in the present invention for label formation on the recording surface of the optical disc.

The pattern of the recording laser used in the formation of the image does not follow the EFM scheme, which is a typical mark / space pattern used for recording data.

In this case, the mark / space pattern follows the image pattern to be formed. However, the mark / space pattern must be a pattern in which spaces exist at regular intervals for the control of the laser power.

5 shows a schematic configuration diagram of an apparatus used for label formation in an optical disc according to the present invention.

The apparatus comprises an optical disc 10, a pickup / motor 11, a signal processing unit 12, a disc determining means 13, an image synchronizing signal forming unit 14, an image editing unit 15, an image encoding unit 16 and It consists of a recording strategy (17).

As the optical disc 10, a disc having a recording surface of a multilayer structure is used. The pickup / motor 11 extracts a signal to be reproduced from the optical disc 10 or records an image on the optical disc 10.

The signal processor 12 modulates and processes the various signals output from the pickup / motor 11 and outputs them as signals to be reproduced.

The disc judging means 13 discriminates the optical disc 10 from the track information among the signals output from the signal processing section 12.

The disc determination means 13 determines whether the optical disc 10 is a disc which can be recorded once or a disc which can be repeatedly recorded from the disc information signal output from the signal processing unit 12, and the optical disc 10 Whether the single-sided single-sided disc, the double-sided single-sided disc, the single-sided double-sided disc or the double-sided double-sided disc is determined.

The image synchronization signal forming unit 14 generates a synchronization signal for aligning the beginning of the image to be recorded in the image area.

The image synchronizing signal forming unit 14 generates an image synchronizing signal using the wobble information of the optical disc 10 or detects rotation of a motor for rotating the optical disc 10 output from the pickup / motor 11. The signal is used to generate an image synchronization signal.

The image editing unit 15 edits the size, color, shape, and the like of an image to be recorded on a part of the recording layer of the disk having a multi-layer recording surface.

The image encoding unit 16 encodes the image edited by the image editing unit 15.

The image encoding unit 16 encodes the edited image so that the laser beam can continuously record the track.

The recording strategy 17 modulates for accurate mark recording of the encoded image.

The modulated image is recorded on the optical disc 10 through the pickup / motor 11 by a synchronization signal for matching the image start area generated by the image synchronization signal forming unit 14.

When the image recording on the optical disc 10 is confirmed after confirmation, the recorded image can be visually viewed.

 According to the present invention, a label can be formed on the recording surface on the optical disc stably without being influenced by the capacity of the data recorded on the recording surface and without the influence of the vibration in a short time.

 As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and modified within the scope of the present invention without departing from the spirit and scope of the present invention described in the claims below. It will be appreciated that it can be changed.
