Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a message writing practice sheet for optical recording disks on which digital information is optically recorded, such as digital audio disks called compact disks. Regarding. (b) Conventional technology Digital audio disks (hereinafter referred to as CDs) called compact disks are described in, for example, "Broadcasting Technology", March 1981 issue, paragraphs 316-317, "Nikkei Electronics", August 1981. 17th issue No. 187-206
Many types are sold by various companies. This conventional, common CD has a high information recording density and is characterized by the ability to play over an hour of extremely high-quality music on one side on a small disc with a diameter of 12 cm. Therefore, brand names, song titles, etc. are printed in areas on the surface opposite to the information readout surface (the surface on which the readout beam is irradiated) as shown in Figure 4, but this is effective in terms of space. There is a lot of space that is unused. On the other hand, in recent years, young people have been giving various items as gifts at Christmas, Valentine's Day, etc., but it is rare to see gift products with audio information, and even if they are, they are often given message cards separately from the products. The drawback is that you have to attach the message card, which makes it expensive, and if you lose the message card, you won't know what gift it was.
In other words, it lacked preservation ability as a souvenir. In view of the above points, the applicant proposed in Utility Model Application No. 62-048241 an optical recording disk provided with a message writing area on the surface in which messages can be written additionally. (c) Problems that the invention aims to solve The above-mentioned message additions to the disk are usually done with an oil-based felt-tip pen, but once written, they cannot be easily erased, so disk buyers are worried that they will make mistakes. I had to write this with great fear. This proposal aims to reduce such concerns. (d) Means for solving the problems The present invention is a message writing practice sheet for an optical recording disk that records digital information inside and has a message writing area on the surface where a message can be written. a disk outline having substantially the same size as the message writing side surface of the optical disk; and within the outline a message writing practice area having substantially the same arrangement and size as the message writing area; By providing at least the following, the above object has been achieved. (e) Effect: You can write a message in the message writing practice area of the message writing practice sheet as if you were writing it directly on the disk, and by writing the message on the surface of the disk while looking at this draft, you can reduce the number of mistakes in writing. (f) Example An example of the present invention will be described with reference to FIGS. 1 and 5. FIG. 4 is a plan view of an optical recording disk, and FIG. 5 is a cross-sectional view of the same. 1 is a transparent disk-shaped substrate made of polycarbonate or the like, and audio information is recorded in pits (concavities) on one recording surface 2. It is digitally recorded in the form of
is provided, and on top of this, for example, an ultraviolet curable resin protective film layer 4 is provided. A printed layer 5 is formed on this protective layer 4 by means such as silk printing as shown in FIG. The printing layer 5 is composed of a plurality of regions 5a, 5b, 5d, and the first region 5b is "Happy".
In the message title area where a greeting title such as "Birthday", "marry Christmas", etc. is formed by printing, only the characters, marks, etc. are the printing layer, but the area around the characters is Characters may be formed negatively as a printing layer. Corresponding to the message title created in this way, one or more songs corresponding to the message title, such as the title "Happy", are displayed on the recording surface 2.
In the case of ``Birthday'', songs such as ``Batsu Pivers Day to You'' are digitally recorded. Therefore, the audio information recording portion is a predetermined area from the lead-in portion on the inner circumferential side of the disc, and the outer circumferential portion is a non-recording portion. By reducing the number of songs recorded in this way, the selling price of the CD is reduced, making it more affordable for young people. Incidentally, the number of recorded songs mentioned above can be changed in various ways according to the needs of consumers. The second area 5a is a message writing area on the surface of which a specific message can be written using one or more types of writing implements (not shown) such as an oil-based felt-tip pen. The third and fourth areas 5c and 5d are areas for appropriately printing and recording various information such as brand names, song titles, composer names, etc. Next, the message writing practice sheet of the present invention will be explained with reference to FIGS. 1 to 3. 6 is a message writing practice sheet having the same shape as the container (not shown) that stores the disk D, and is either stored in the container or attached to the container and integrated with the wrapping paper (not shown) that wraps it. will be stored and sold. As shown in FIG. 1, the paper b is a rectangular paper in which the shape and written contents of the write-once side surface 5a of the disk D are printed and transferred (copied) as they are, except for the hue, saturation, and brightness. Of course, the disk outline 8, the message writing practice area (corresponding to the second area 5a) 5A, etc. are the same as the disk in terms of shape and arrangement.
As shown in FIG. 2, on the back side of the paper 6 are written instructions for writing the message, and the paper 6 also serves as an instruction manual. In the above configuration, to write a message on disk D , as shown in FIG . By writing the same message 7 in the second area 5a of the disk D , writing errors can be minimized. Of course, if a mistake is made during the draft stage, it can be corrected on the paper 6, or a spare draft paper may be prepared separately and the draft may be written on it again. Note that the present invention is not limited to the above-mentioned embodiments, and the contents written in the third and fourth areas 5c and 5d in the disk outline 8 of the paper 6 do not need to be drafted. It is sufficient if the storage area 5a has substantially the same size, arrangement, and type as the disk surface. Further, although it is not necessarily necessary to use the same as the instruction manual, it is economical to use the paper more effectively. (g) Effects According to the present invention configured as described above, by drafting the message to be added to the disk in advance on the message writing practice sheet, it is possible to write the message on the disk with confidence, and to avoid mistakes. It has great effects such as being able to reduce the amount of water used.
