Description

SUPPORT D'ENREGISTREMENT PHONOGRAPHIOUEET/OU
VIDEOGRAPHIOUE COMESTIBLE
L'invention concerne un support d'enregistrement phonographique et/ou vidéographique comestible.PHONOGRAPHIC RECORDING MEDIUM AND / OR
EDIBLE VIDEOGRAPHY
The invention relates to an edible phonographic and / or videographic recording medium.

Traditionnellement, les supports d'enregistrement phonographique, et notamment les disques, sont constitués d'une matière thermoplastique (la vinylite), et sont obtenus généralement par pressage. De la sorte, on définit à leurs surfaces des microsillons gravés, dont l'interaction avec une tête de lecture permet la restitution auditive. Traditionally, phonographic recording media, and in particular discs, are made of a thermoplastic material (vinylite), and are generally obtained by pressing. In this way, engraved microgrooves are defined on their surfaces, the interaction of which with a read head enables auditory reproduction.

Les disques compacts et vidéo-disques, sont recouverts quant à eux d'un revêtement métallique et sont perçés d'orifices traversants de très faible dimension, dont la séquence, détectée par un faisceau de lumière cohérente, typiquement un faisceau laser, permet également de restituer soit des sons, soit des images associées à une bande sonore. Compact discs and video discs are covered with a metallic coating and are pierced with very small through holes, whose sequence, detected by a coherent light beam, typically a laser beam, also allows restore either sounds or images associated with a soundtrack.

On a également proposé des disques d'enregistrement phonographique, destinés à être sucés, croqués, mâchés et mangés, donc des disques comestibles, susceptibles également d'être gravés d'une manière ou d'une autre, pour pouvoir restituer un enregistrement sonore ou visuel. Néanmoins, et comme on peut le voir sur la figure 1 représentant un tel disque, la tête de lecture est soumise d'une part à la force centrifuge dûe à la rotation du disque, et d'autre part à la résistance des microsillons. n apparaît que, compte tenu de l'utilisation d'un matériau relativement mou, et en tout cas offrant peu de résistance, la tête de lecture est entraînée vers l'intérieur du disque, et sectionne les crêtes des microsillons, de sorte que le disque n'est plus audible. Phonographic recording discs have also been proposed, intended to be sucked, chewed, chewed and eaten, therefore edible discs, also capable of being burned in one way or another, in order to be able to reproduce a sound recording or visual. Nevertheless, and as can be seen in FIG. 1 representing such a disc, the read head is subjected on the one hand to the centrifugal force due to the rotation of the disc, and on the other hand to the resistance of the microgrooves. It appears that, taking into account the use of a relatively soft material, and in any case offering little resistance, the read head is driven towards the inside of the disc, and cuts the crests of the microgrooves, so that the disc is no longer audible.

L'objet de l'invention est de proposer un disque comestible de ce type, mais susceptible d'être écouté plusieurs fois, compte tenu de son profil particulier. The object of the invention is to provide an edible disc of this type, but capable of being listened to several times, taking into account its particular profile.

Selon l'invention, le support d'enregistrement phonographique et/ou vidéo graphique est constitué par une plaque, réalisée en un matériau comestible, munie en son centre d'un orifice de positionnement sur un appareil de restitution auditive et/ou visuelle, et comporte un microsillon au niveau duquel est gravé un enregistrement audio et/ou video. il se caractérise en ce que l'épaisseur de sa section transversale varie de la périphérie vers le centre. According to the invention, the phonographic and / or graphic video recording medium consists of a plate, made of an edible material, provided in its center with a positioning orifice on a hearing and / or visual rendering device, and includes a microgroove on which an audio and / or video recording is engraved. it is characterized in that the thickness of its cross section varies from the periphery to the center.

En d'autres termes, l'invention consiste à conférer à un support comestible un profil particulier, propre à opposer à la progression radiale de la tête de lecture, la résistance nécessaire pour induire une progression de celle-ci selon le microsillon gravé dans ledit support. Pour ce faire, on vise à diminuer la force exercée par la tête de lecture sur les crêtes du microsillon, en faisant intervenir la masse de ladite tête dans la composante non verticale de la force centrifuge, et ce, en inclinant la face supérieure du support
Avantageusement, la variation de cette épaisseur est continue et linéaire, de sorte à définir un plan. De manière avantageuse, l'angle d'inclinaison de ce plan de variation par rapport au plan de la base du support est compris entre 2 et 5 et avantageusement voisin de 3 . In other words, the invention consists in giving an edible support a particular profile, capable of opposing the radial progression of the read head, the resistance necessary to induce a progression of the latter according to the microgroove engraved in said support. To do this, we aim to reduce the force exerted by the read head on the crests of the microgroove, by involving the mass of said head in the non-vertical component of the centrifugal force, and this, by tilting the upper face of the support.
Advantageously, the variation of this thickness is continuous and linear, so as to define a plane. Advantageously, the angle of inclination of this variation plane relative to the plane of the base of the support is between 2 and 5 and advantageously close to 3.

La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront mieux de l'exemple de réalisation qui suit donné à titre indicatif et non limitatif à l'appui des figures annexées. The manner in which the invention can be implemented and the advantages which ensue therefrom will emerge more clearly from the example of embodiment which follows, given by way of indication and without limitation in support of the appended figures.

La figure 1 est comme déjà dit une représentation schématique d'un disque comestible de l'art antérieur. Figure 1 is as already said a schematic representation of an edible disc of the prior art.

La figure 2 est une représentation schématique en détail d'une coupe transversale d'un disque conforme à l'invention. Figure 2 is a schematic representation in detail of a cross section of a disc according to the invention.

La figure 3 est une représentation schématique d'une coupe transversale totale du disque. Figure 3 is a schematic representation of a total cross section of the disc.

La figure 4 est une vue en pIan du disque conforme à l'invention. Figure 4 is a plan view of the disc according to the invention.

Comme on peut le voir en détail sur la figure 2, le disque (1) présente une section transversale, dont l'épaisseur augmente du bord périphérique (7) vers le centre (4) du disque. De manière connue, ce centre (4) est perçé d'un orifice, notamment traversant, permettant son positionnement sur l'appareil de lecture.  As can be seen in detail in Figure 2, the disc (1) has a cross section, the thickness of which increases from the peripheral edge (7) towards the center (4) of the disc. In known manner, this center (4) is pierced with an orifice, in particular through, allowing its positioning on the reading device.

Comme on peut le voir sur la figure 2, cette épaisseur croît linéairement, et définie de sorte un plan moyen, dont l'inclinaison par rapport à l'horizontale, c'est à dire par rapport à la base (2) du disque varie entre 2 et 5 et est typiquement voisine de 3 ". De la sorte, la tête de lecture (5), en contact avec le sillon concentrique (6) subit elle-même un ascension du bord (7) vers le centre (4). De fait, le poids, grandeur vectorielle de cette tête de lecture (5), diminue l'action de cette dernière sur les crêtes du sillon (6), compte tenu de l'inclinaison donnée à la face supérieure (3) du disque. On s'affranchit de la sorte de toute destruction des dites crêtes, permettant alors de ré-écouter un certain nombre de fois l'enregistrement gravé dans le microsillon. As can be seen in Figure 2, this thickness increases linearly, and defined so as a mean plane, whose inclination relative to the horizontal, that is to say relative to the base (2) of the disc varies between 2 and 5 and is typically close to 3 ". In this way, the read head (5), in contact with the concentric groove (6) itself undergoes an ascent from the edge (7) towards the center (4) In fact, the weight, vector quantity of this read head (5), reduces the action of the latter on the ridges of the groove (6), taking into account the inclination given to the upper face (3) of the disc. We are thus freed from any destruction of the said crests, thus making it possible to listen to the recording engraved in the microgroove a certain number of times.

Compte tenu de son caractère comestible, le disque ainsi réalisé peut être consommé. Given its edible nature, the disc thus produced can be consumed.

De tels disques sont avantgeusement réalisés en chocolat. Le microsillon est réalisé par moulage à chaud sur une matrice gravée en négatif, et présentant le profil incliné conforme à l'invention. La réalisation du disque s'effectue alors en versant simplement le chocolat chaud et liquide dans un moule, par exemple en matière plastique. Une fois le chocolat refroidi, on procède au démoulage pour obtenir le disque. Such discs are advantageously made of chocolate. The microgroove is produced by hot molding on a matrix engraved in negative, and having the inclined profile in accordance with the invention. The disc is then produced by simply pouring hot and liquid chocolate into a mold, for example made of plastic. Once the chocolate has cooled, it is removed from the mold to obtain the disc.

il va de soi que l'on peut remplacer le chocolat par toute autre matière comestible, et notamment du sucre. Il suffit dans ce cas d'adapter la profondeur du sillon et l'espacement entre deux tours de sillon successifs, pour tenir compte de la différence de comportement de la matière, notamment lors de son refroidissement, et notamment de la plus ou moins grande amplitude du retrait. it goes without saying that chocolate can be replaced by any other edible material, and in particular sugar. In this case, it suffices to adapt the depth of the furrow and the spacing between two successive furrow turns, to take account of the difference in behavior of the material, in particular during its cooling, and in particular of the greater or lesser amplitude. of withdrawal.

Le disque ainsi réalisé peut avantageusement être proposé dans une pochette de protection, susceptible de porter une publicité ou annonce.  The disc thus produced can advantageously be offered in a protective pouch, capable of carrying an advertisement or advertisement.
