として記録されているものである。Recently, a video disc as shown in FIG. 1 has been proposed as a video program source. In FIG. 1, (1) indicates an optical video disc, and this video disc ill has a recording section (2) on which a video signal is recorded as recording information.

録情報の内容を知ることができるようになされている。This type of video disc (1) is produced by irradiating a mask master disk, which is a glass substrate with a polished flat surface and evenly coated with photosensitive paint (photoresist), by irradiating a laser beam modulated in accordance with the video signal. After exposing the resist to light and developing the exposed mask master, two-sokel electroforming is performed, and when it is peeled off, a mask is completed.This mask becomes a nickel stamper.The nickel stamper is molded with transparent plastic, and this molded It is made by steaming an aluminum reflective film onto transparent plastic and then applying a protective film made of glass nac. The optical video disc (1) constructed in this way is provided with a label section (3) on the inner circumferential side thereof for displaying the contents of recorded information recorded in the recording section (2). 3) makes it possible to know the contents of recorded information.

ドリーダを必要とする不都合があった。However, since such optical video discs (11) use photoresist, it is difficult to manually cut and engrave the master disc like a conventional record disc on which audio signals are recorded. Also, even if the engraving was done at this stage, there was an inconvenience that subsequent processes such as molding were difficult.Therefore, after the mask was made, marks were put on the mask to identify it.For this reason, at the same time, When making a large number of multi-build items, there was a risk of mistakes such as the mixing of different types of items.Also, there was a risk that the markings were not made at the same time as the information was recorded on the video disc (1). , only the engraving may be done manually in a separate process,
In this way, there is a possibility that an error may occur in the manual marking process that is separate from the recording of information. Furthermore,
If the video disc (1) is only engraved manually, it is very difficult to place the engraved position of the video disc (11) in a predetermined position and automatically identify it. Character recognition for video discs (
It is being considered to add a barcode (4) to 1). However, it is difficult to record the code (4) by mechanically cutting the video disc (11), and the barcode (4) recorded linearly in this way is difficult to record. It is not possible to read the video disc fil while it is being rotated, and therefore a special barcode reader is required to scan the barcode (4) and read the barcode (4).

に読み取らせることができる。As described above, according to the present invention, in the process of irradiating the mask master (5) with the laser beam LH that is optically modulated according to the video signal, the character code (4a ) and barcodes (4b)7, character codes (4b) that could not be recorded on optical video discs (11) were recorded on conventional records. 4a)
and barcode' (4b) can be recorded without leaving problems with moldability, and the video signal that is recorded information and the character code (4b) that displays this recorded information can be recorded.
4a) and the barcode (4b), and there is no chance of recording incorrect character codes (1d) and barcodes (4b) on the video disc (1). In addition, since the content of the recorded information recorded on the recording section (2) of the video disc (1+) is displayed using a character code (4a) and a barcode (4b), it is not possible to display the content of the recorded information recorded on the recording section (2) of the video disc (1+) using a character code (4a) and a barcode (4b). tJ automatically by machine
When distinguishing characters, there is no need for expensive means such as character recognition, and the distinction can be made using an inexpensive barcode reader that converts the shading of the pattern into a high-level signal @1" and a low-level signal "0". In addition, since it is possible to know the inner valley of the recorded information by looking at the character code (4b), there is no mistake even when manually pasting a label on the syllabary part (3). Furthermore, a bar code (4b
) should match the radial direction of the video disc (1), and when the machine automatically identifies the video disc (1), the barcode cannot be read on the barcode as before. Instead of using a special barcode reader to scan and read barcodes, you can read the barcode (4b) with a normal barcode reader while rotating the bidet disc (1). , the barcode (4b) can be read easily and accurately without having to go through the trouble of positioning it.
