Description

The present invention relates to a method for producing a compact-type compact disc -Rom.

The purpose of this method is to obtain a compact disc of small dimensions so it can be considered as a business card or as a postcard.

Another essential feature is to be able to have a large amount of information housed in a small format, so that the business card thus produced can serve as an elaborate curriculum vitae or advertising medium.

Standard compact discs have a maximum diameter of about 120 mm. Rarely there are compact discs of smaller size. There are mini audio discs of about 60 mm diameter for recording the usual audio compact discs.

To our knowledge there are CD-ROMs allowing the use of a business card with pins to center the CD in the reader. Brand GOLDIE these CD-ROMs are limited to 20 megabytes. Of different manufacture to the same dimensions and similar capacity, the company MBBC diffuses a card centered on the CD player of diameter 8 cm.

It therefore seemed plausible to cut a compact disc to make it suitable for its intended use.

The cutting processes have been the subject of various patents among which the patent LARA Consultants, LAROCCA VVO 95.00282 deals with a method of laser cutting a piece of ferrous material. Exothermic reactions of iron oxidation make it possible to obtain complex reactions carried out under conditions of dynamic equilibrium.

The patent PORTNER FR. & 2.612. 1 13 relates to a cutting device of various shapes in soft materials. The device comprises a base provided with a groove allowing the sliding of a blade holder on which I is fixed and allows the cutting of the material.

The patent @JiECARHONE FR.A.2.550. 125 discloses a machine for cutting blocks of cellular plastic material using heating son. These methods do not make it possible to obtain a neat cut without splinters of the materials, in particular of the organic layer and of the support substrate. In addition it is difficult to obtain a specific CD in good conditions of precision and reasonable prices without resorting to fabrications in very large series.

Under these conditions an implementation from existing CD-Rom was the only solution possible. The method according to the invention comprises the following phases A - Blank CD-ROM choice according to the destination of the finished product B - Putting a mask on the back of the disk delimiting the useful surface. C - Painting of both sides front and back of the disc.

D - Cutting the CD-Rom to final dimensions. r r, _._ # a C - mask removal.

F - Engraving computer data on the back of the disk.

G - Collage of an identification and I or advertising label on the front of the disc.

Advantageously, phase A comprises any one of the following steps A 1 - Choice of the virgin CD-ROM of standard standard dimensions of 120 mm in diameter to obtain a postcard format.

A 2 - Choice of virgin CD-ROM with specific dimensions of 80 mm diameter to obtain a business card format.

According to another characteristic, phase B comprises the following steps: B 1 - Choice of a self-adhesive translucent adhesive sheet.

B 2 - Cutting of the mask to the dimensions corresponding to the intended use in A 1 or A 2 in the form of a disc pierced at its center.

B 3 - Gluing of the mask thus made on the back of the disc. Preferably phase C comprises the following steps: - Spraying an acrylic paint on all of the two faces of the disk, said spraying having for purposes on the front of the disk to plaster and stick on the transparent plastic substrate the layer organi the layer reflective, the protective varnish, it also aims the back of the disc to soften the transparent plastic substrate facilitating the cutting of the disc C 2 - drying paint.

According to a preferred embodiment, the phase D comprises the following steps D 1 - Realization of a support consisting of a plastic plate having a plurality of cutouts for holding in position each of the disks force-fitted into the cuts.

D 2 - Cutting each of the discs using a high-pressure water jet machine.

D 3 - Drilling with this same water jet machine a hole for a commercial application of the keychain type, especially for the business card format.

D 4 - Extraction of discs cut from the support. Drying. Advantageously the removal of the mask; is operated manually from the center of the disk so that the paint delimiting the useful surface of the disk is not flaked off.

According to another characteristic, the engraving or pressing of the computer data is conventionally operated on a limited surface making it possible to store, on the card format, about 40 Megabytes.

The method according to the invention makes it possible to obtain compact discs of reduced dimensions presenting forms similar to a business card or a postcard.

Other features and advantages will appear on reading the description of the process covered by the invention to obtain a business card format from a compact disc of reduced dimensions of approximately 80mm diameter. This type of embodiment is given by way of example iliustratii nonlirai with reference to the accompanying drawings in which Figures I are schematic views of a blank disc FIGS. 2 are schematic views of the production of an identity card . FIG. 1A shows a schematic plan view of a blank disc having a diameter of approximately 80 mm on the front side, showing through the varnished layer 4 the silvered reflective layer 3.

FIG. B is a diagrammatic plan view of this blank disc on the back showing transparent plastic support in polycarbonate 1.

FIG. 1C shows a schematic sectional view of the blank compact disk comprising the following successive layers. From the backside B on the transparent polycarbonate support 1 is fixed the organic layer 2 on which the information will be printed. On this layer is deposited a reflective layer 3 itself protected by a layer of varnish 4.

FIG. 2A shows a schematic view without the label 6 in the front side of the business card made by implementing the method according to the invention in FIG. 2B on the back side.

According to a schematic in section 2C, the successive layers of the blank compact disk consisting of layers 2 - 3 - 4 deposited on the transparent plastic support in polycarbonate 1 are shown.

The blank compact disc being chosen is carried out first in phase B cutting a mask consisting of a plain translucent self-adhesive adhesive trademark VENILIA (Ref i 1 û 1 û2ûj.

This mask is cut to an outer diameter of <B> 060 </ B> mn i having a central hole diameter 15 mm. It is attached to the back of the compact disc.

Then, according to phase C, an acrylic spray is applied using an aerosol spray, a layer 5 on the front and 8 on the back.

This paint, recto, plate and glue the organic layer 2 the polycarbonate substrate 1. It also aims, side back softened this substrate and facilitate cutting and avoid flaking. After drying, the cutting phase is carried out. To do this, a plastic plate approximately 2 mm thick is used in which cuts of diameter 79.8 mm have been made so that the disk with a diameter <B> 80 </ B> mm is engaged in strength and is maintained during the cutting operation.

This cutting is performed on a high-pressure water jet machine. It allows to cut at high speed each of the discs so that the width of the compact disc is about 63 mm. We take advantage of this operation to drill a hole 9 of 3 mm for a commercial application like keychain.

These operations being performed, the visit cards thus produced are extracted, allowed to dry and the following operation is carried out according to phase E consisting of extracting the mask. This is done manually so that the paint does not peel off. In this case, only a crown of paint on the backside is left, allowing a surface width of approximately 7 mm to be etched, which makes it possible to store 43 1/2-megabytes of information. The engraving or pressing then performed conventionally with a laser device.

On the front is then pasted a label ô advertising identification.

Thus, by implementing the method according to the invention, this business card format is obtained. Starting from a blank compact disc of diameter <B> 120 </ B> mm standard by proceeding to similar cuts one obtains a rectangle forming postcard allowing to house a greater number of information. The method according to the invention can be applied to new media type allowing the pressing of much more information.

modifications that may be made by those skilled in the art to the above process which, without altering the original arrangements, are merely technical equivalents, are also within the scope of the present invention.
