Definitions
- the present invention relates to compact discs (CDs) and digital video discs (DVDs),
- the disc tends to skip when it is read by a laser in a CD or DVD player.
- the disc protector comprises a rigid transparent plastic disc
- water-soluble adhesive is applied to one side of the optical
- media disc protector such as in an inner ring around the center-hole, and a peripheral
- a protective removable backing may be supplied over the temporary adhesive
- This embodiment is used by removing the backing and
- the disc protector If the disc protector is damaged, it can be removed from the optical media by
- the transparent plastic disc is formed in a substantially
- the temporary pressure-sensitive adhesive is applied to one side of
- each of the tabs, and a removable backing may be supplied to protect the adhesive until
- This embodiment is used by removing the backing and applying the disc
- FIG. 1 is a perspective view of a disc protector 2 in accordance with a first
- FIG. 2 is a front view of the disc protector 2 of FIG. 1.
- FIG. 3 is a front view of a disc protector 20 in accordance with an alternative
- the present invention is a new and improved apparatus and method for protecting
- the present invention comprises a transparent protective
- the transparent cover 2 is preferably formed of plastic, however, other materials
- Rigid transparent plastic material is suitable such as polycarbonate,
- the protective cover 2 is circular and substantially identical in size to a CD/DVD
- the protective layer except it is preferably half the thickness of the CD/DVD.
- Conventional CD and DVDs have a substrate diameter of 120mm, and a thickness of 1.2mm.
- cover 2 is approximately 120mm wide and 0.6mm thick. At this thickness, the protective
- cover 2 will not inhibit the ability of the CD or DVD to be read in an appropriate player.
- the transparent properties of the cover 2 enable the laser to still be able to read
- the protective cover 2 is formed with a center hole
- the protective cover 2 is preferably removable so that if the protective cover
- a new protective cover 2 is damaged and not the actual CD/DVD.
- the present invention contemplates two methods for applying the removable
- the protective cover 2 is applied to the read side
- the protective cover 2 is provided, water dispersed polyurethane resin being one example.
- the protective cover 2 is provided, water dispersed polyurethane resin being one example.
- adhesive 4 may be placed around the center hole 12, and a second ring of adhesive 6 may
- the protective cover 2 may further include a thin plastic film backing that covers the adhesive until the user is ready to apply the cover to a disc, similar to a self-adhesive postage stamp. Once the adhesive surfaces 4, 6 are exposed, the protective cover 2 is gently pressed together with the disc. For ease of use and accuracy, either the protective cover 2 or the disc may be placed in a disc holder or jewel case while the other component is pressed against it. This method leaves little room for error when aligning the center holes on the components.
- the disc protector in a second embodiment includes a plastic disc 20 with a plurality of axial tabs 26 protruding from its periphery.
- temporary adhesive strips 22 are applied to one side of each tab 26, as shown in FIG. 3.
- the adhesive strips 22 for this method need not be water-soluble. Rather, they can be any type of removable adhesive strips such as 3MTM brand Removable Repositionable Tape strips. While four adhesive strips 22 are shown, the present invention contemplates that any number of adhesive strips 22 may be used.
- the adhesive strips are affixed to the protective cover 20 and have a plastic film or paper backing 24 that may be peeled away to expose the adhesive.
- the strips 22 are pulled over the top of the disc and gentle pressure is applied to ensure that the adhesive strips 22 are in contact with the disc.
- the tabs 26 with the adhesive strips 22 are preferably long
- a disc holder (or jewel case) may be used for accuracy when aligning the disc and the protective cover.
- the disc surface of CDs and DVDs is easily scratched from handling and
- the disc may either skip

Abstract
L'invention concerne un dispositif de protection de disque support optique (10) comprenant un disque en plastique transparent (2, 20) présentant une configuration sensiblement circulaire et pourvu d'un trou (12) en son centre. Dans un mode de réalisation, un adhésif temporaire hydrosoluble (4, 6), appliqué sur un côté du disque en plastique (2) au niveau de l'anneau intérieur, adjacent au trou central (12), et de l'anneau extérieur périphérique, fixe le disque en plastique (2) sur le disque support optique (10). Dans un autre mode de réalisation, des bandes adhésives temporaires autocollantes (22) fixent le disque en plastique (20) sur le disque support (10). Le laser d'un lecteur de disque classique peut alors lire le contenu d'un disque support optique (10) à travers le disque en plastique (2, 20). Si un dispositif de protection de disque est endommagé, il peut être facilement retiré et remplacé.
