2. Description of the Related Art Conventional optical discs are rotated with the recording surface facing downward, and a laser beam is irradiated from the bottom, and information on the recording surface is read by the reflected light. A transparent protective layer of a certain thickness is formed on the surface of this recording surface, and even if fine dust adheres to the surface of the transparent protective layer, the focus of the irradiated light will not be on the surface of the transparent protective layer. Since it is set to match the position of the recording surface, dust does not interfere with information reading.

However, since this transparent protective layer is hard and requires a certain thickness, it cannot be attached to books, magazines, or product introduction pamphlets, resulting in poor distribution.

The applicant has already proposed a flexible laser disk in the form of a sonosheet whose disk body is flexible, a method for manufacturing the same, and an apparatus for manufacturing the same (Japanese Unexamined Patent Publication No. 63-1
No. 4340). This flexible laser disk (flexible disk) consists of a transparent hard plate of a predetermined thickness (
By stacking the disk on top of the disk (with an adapter) or bonding it to the adapter with adhesive, it can be played on a commonly used disk playback device.

[0005]

[Problems to be Solved by the Invention] However, when a flexible disk is used simply by stacking it on top of an adapter, the disk becomes unstable during rotation, and dirt may enter the gap between the disk and the adapter. , the read error rate is high. Additionally, if the disc was not handled with care, it could crease and become unusable.

On the other hand, when attaching a flexible disk to an adapter using adhesive, if it is attached in the wrong position, it cannot be corrected later and the disk becomes unusable. I can't leave it to you.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a flexible disk provided with an adhesive part that anyone can easily attach to an adapter and that can keep the error rate due to dust to a low level. .

Another object of the present invention is to provide a flexible disk attachment aid that allows easy and accurate positioning of the flexible disk on the adapter.

[0009]

[Means for Solving the Problems] In order to solve the above-mentioned problems, a flexible disk provided with an adhesive section according to the present invention includes a flexible disk body having a recording section on one side, and a playback of the disk body. At least a portion of the surface has an adhesive portion coated with a removable adhesive.

[0010] The adhesion aid for flexible disks is as follows:
A flexible disk adhesion aid for adhering the flexible disk to a hard, transparent donut-shaped adapter, comprising: a protrusion that fits into the center hole of the adapter; and an outer periphery that fits into the center hole of the flexible disk. It has a configuration with side surfaces.

Embodiments Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a bottom view showing a first embodiment of a flexible disk provided with an adhesive portion according to the present invention, and FIG. 2 is a cross-sectional view taken along line A-A in FIG. 1 together with an adapter. be.

In the first embodiment, the flexible disk 4
Adhesive parts 2a and 2b are provided on the inside and outside of the recording part 1. When the user uses the flexible disk 4, it is attached to the adapter 5 using an attachment aid 70 as shown in FIGS. 8 and 9.

FIG. 8 is a plan view showing an embodiment of the flexible disk attachment aid according to the present invention, and FIG. 9 is a cross-sectional view taken along line BB in FIG. As shown in FIGS. 8 and 9, the attachment aid 70 has a donut-shaped adapter 5 to which the flexible disk 4 is to be attached.
The flexible disk 4 has a protrusion 71 that fits into the center hole of the flexible disk 4 and an outer circumferential side surface 72 that fits into the center hole of the flexible disk 4. The outer peripheral side surface 72 is sloped so that the hole 3 of the flexible disk 4 can be easily introduced from above.

When attaching the flexible disk 4 to the adapter 5, the protrusion 71 of the attachment aid 70 is fitted into the center hole of the adapter 5, and the protrusion 71 of the attachment aid 70 is inserted into the hole of the flexible disk 4 from above along the slope of the outer peripheral side surface 72. 3, the flexible disk 4 is attached to the adapter 5 using the adhesive parts 2a, 2b, etc. and pressed, and then the adhesion aid 70 is pulled out upward by hooking a finger into the hole 73.

The user only needs to have one attachment aid 70, and if the flexible disk to which the adapter 5 is attached becomes unnecessary, it can be peeled off and a new flexible disk attached. It's so good that you can use it over and over again.

FIG. 3 is a sectional view showing a second embodiment of a flexible disk provided with an adhesive portion according to the present invention, along with an adapter. In the flexible disk 14 of the second embodiment, the adhesive portion 12 is formed only on the outer periphery. Further, as the adapter 15, one in which an upward circumferential band-shaped protrusion 16 is provided around a central hole is used. If such an adapter 15 is used, the protrusions 16 function similarly to the adhering aid 70, so that accurate adhesion positioning can be performed even without the adhering aid 70.

FIG. 4 is a diagram showing a third embodiment of a flexible disk having an adhesive portion according to the present invention. In the third embodiment, an adhesive section 22 is formed over almost the entire surface of the recording section of the main body of a flexible disk 24. At this time, a gap is created by inserting the outermost peripheral part of the adhesive part 22 from the peripheral part of the main body of the flexible disk 24 and the peripheral part of the adapter 25. In this way, by inserting a fingernail or the like into this gap, a starting point for re-peeling can be created. In addition, FIGS. 1 to 4 mentioned above
In the examples shown in , there is almost no possibility that dust will enter the surface of the recording section.

FIG. 5 is a diagram partially showing a fourth embodiment of a flexible disk having an adhesive portion according to the present invention. As shown in FIGS. 1 to 3, there is an adhesive section 32 on the outside of the recording section 1.
