TECHNICAL FIELD AND BACKGROUND OF THE INVENTION

This invention relates to a label for an optical disk. Optical disks presently take many forms, and include plastic disks which contain digital data which may represent computer software, music, video, graphics and many other types of digital data. Such disks are presently made in many sizes and are referred to by different names, for example, CD's, compact disks, optical disks, DVD's, and include unrecorded disks which can be "burned" by consumers and disks which are capable of being recorded and then re-recorded. These disks are typically circular.

Optical disks are also now made and sold which have irregular shapes, and are used for many purposes including business advertising. Such disks can be formed in virtually any shape so long as they will fit into and function in a disk player. One such shape commonly made and distributed is a "business card" disk, which comprises an optical disk which has been cut down in size so that two of the opposing sides are parallel, and the other two opposing sides are convex. The principal requirement for such disks is that the data area exist as a continuous annular area symmetrically positioned around the center hole by which the optical disk is placed on the spindle of a disk player. Such disks are approximately the size of a business card, or somewhat larger.

This application relates to all types of optical disks which have a hole formed in them by which they are rotated during playback. The hole is required not only for playback of the optical disk, but during manufacture, during which large stacks of optical disks are manipulated and transported on long rods or spindles.

The existence and necessity of the hole presents a significant disadvantage in the use of optical disks as advertising and promotional products, since the hole is relatively large in relation to the overall size of the disk, particularly in the smaller format disks and those with irregular shapes. For example, with the so called "business card" optical disk, the location of the hole has heretofore required that text and graphics material be sized and arranged to fit around the hole, limiting the size of the text and graphics and thus the attractiveness and distinctiveness of the text and graphics material.

Text and graphics labels are generally applied to the optical disk by silk screening onto one side of the disk, or by applying a paper or foil label to one side of the disk. The silk screening process avoids the hole in the center of the disk, and paper labels include a hole which is aligned with the hole in the disk. As used in this application, the term "label", except as otherwise defined or clear from context, refers to a means by which text and/or graphics material is applied to the disk, whether by silk screening, application of a sheet label, or otherwise.

The invention disclosed in this application permits text and/or graphics material to be applied to the center portion of an optical disk, including the area occupied by the hole in the center of the disk.

DESCRIPTION OF THE PREFERRED EMBODIMENT AND BEST MODE

Referring now specifically to the drawings, a label according to the present invention is illustrated in FIG. 1 and shown generally at reference numeral 10. Label 10 is any suitable sheet material 11, such as paper or card stock, metal or plastic foil, or other plastic sheet material. Label 10 can be shaped to fit onto any optical disk of any size or shape. A plurality of slits 12 are formed in the sheet 11 and converge and intersect to form a star-shaped area defined by adjacent sheet segments 13. The slits 12 are placed in the label 10 in registration with the hole 23 so that when the label 10 is applied to the optical disk 20, the sheet segments 13 overlie the hole 23. The slits may be cut by any suitable method. As is shown in FIG. 2, the label 10 completely covers the hole 23 and renders it invisible. The slits 12 are only faintly visible, and lie in the plane of the sheet 11. This permits text and or graphics material to be placed on the label 10 without regard to the existence of the hole 23 in the optical disk 20. See FIGS. 6, 7 and 8.

As is shown in FIGS. 3, 4 and 5, the sheet segments 13 are deformed upwardly as a spindle is extended through the hole 23. When the spindle is removed, the sheet segments 13 return to the plane of the sheet 11. If necessary, the sheet segments 13 can be pressed downwardly to resume a position in the plane of the sheet 11.

As is shown in FIGS. 6, 7 and 8, optical disks 30, 40 and 50 illustrate that text and/or graphics material can be placed on the labels 10A, 10B, 10C to occupy the area over the hole.

Referring now to FIG. 9, an optical disk 55 is shown in cross-section, and includes a hole 56 covered by an integrally-molded, very thin web 57 which serves as a substrate which can be silk-screened or otherwise provided with text or graphics material, or merely painted with a desired color. The web 57 is provided with slits 58 arranged in a pattern such as shown above. The slits 58 permit the adjacent segments 59 to be deflected upwardly by an object such as a spindle inserted through the hole 56, as described above. The thickness and thus the flexibility is determined empirically based upon the plastic material from which the optical disk is molded.

Referring now to FIGS. 10 and 11, an insert 60 is provided for being placed on an optical disk 65 in the hole 66. Insert 60 is formed of a thin annular ring 61 onto which is applied a sheet 62 having slits 63 which function as described above. It may be necessary to enlarge the hole 66 to the extent necessary to accommodate the thickness of the ring 61. Preferably, the insert 60 is applied to the optical disk 65 by means of a press fit. The insert is particularly desirable when the label of the optical disk 65 is to be applied by means of silk-screening rather than by a sheet label, such as a label 10, 10A, 10B or 10C.

Referring now to FIGS. 12 and 13, a small label 70 is shown which is sized to fit over the hole in the optical disk and a small surrounding area. The label 70 is formed of a sheet material 71 which is provided with slits 72, as described above. The label 70 is applied over any optical disk 75 with a hole 76 in the center, which may then be, for example, silk-screened. The silk-screened design would therefore print onto the label 70 along with the rest of the surface of the disk 75. Alternatively, the label 70 may be applied to a previously silk-screened optical disk, in which case the label 70 must be oriented to match the previously applied text or graphics if required by the pattern.

FIGS. 14 and 15 illustrate a further embodiment 90 wherein a disk body 91 has a hole 92 covered by an integrally-molded, very thin web 94 that serves as a substrate which can be silk-screened or otherwise provided with a label 96 with text and/or graphics material 97, or merely painted with a desired color. As distinct from the disk 55 shown in FIG. 9, the web 94 is solid. According to one embodiment of the invention the web 94 is sufficiently thin that it can easily be broken away from the surrounding annular edge of the disk body 91 by which it is integrally-formed with the disk body. See FIGS. 16 and 17. This is suitable in a situation where, for example, the disk distributor or advertiser is principally interested in the initial appearance of the disk 90 before purchase, and is not concerned with whether some of the label 96 is later removed by breaking out the web 94 and discarding it when the disk 90 is first used. An even thinner annular weakness line (not shown) may be formed at the point of juncture between the web 94 and the disk body 91 to further facilitate separation of the web 94 from the disk body 91 and to provide a clean, smooth break line. While the thickness of the web 94 will vary based on materials used, in general the web 94 should be about {fraction (1/10)}th the thickness of the disk 90.

Examples of the disk 90 in different shapes are shown in FIGS. 18, 19 and 20, with the integral web 94 removable by breaking it away from the surrounding disk body 91.

As is shown in FIG. 21, a label 100 is comprised of a thin patch 101 of film material with an adhesive on a back side and suitable for being printed on the front side. The patch 101 is provided with several intersecting, radially-extending slits 102. As is shown in FIG. 22, the label 100 is positioned on a disk 105 over a hole 106 formed in a disk body 107. The label 100 sized to be approximately 5-20 percent larger in diameter than the hole 106 to be covered, so that the peripheral area of the label 100 overlies the hole and is adhered to the disk body in the marginal area adjacent the hole 106. The slits 102 function in the manner shown in FIGS. 4 and 5 to permit the spindle to deflect the segments of the patch 101 defined by the slits 102. If desired, the label 100 can be removed by raising a corner sufficiently to grasp it between two fingers, and then pulling it to detach it from the disk body 107.

As is shown in FIG. 23, a label 110 is comprised of a thin patch 111 of film material with an adhesive on a back side and suitable for being printed on the front side. As is shown in FIG. 24, the label 110 is positioned on a disk 115 over a hole 116 formed in a disk body 117. The label 110 sized to be approximately 5-20 percent larger in diameter than the hole 116 to be covered, so that the peripheral area of the label 110 overlies the hole 116 and is adhered to the disk body 117 in the marginal area adjacent the hole 106. The label 110 can be printed on by silk-screening or otherwise, so that desired text or graphical material can be applied over the entire top surface of the disk 115. If desired, the label 110 can be removed by raising a corner sufficiently to grasp it between two fingers, and then pulling it to detach it from the disk body 117. The label 110 can be made sufficiently thin and resilient that the spindle will deflect the label 110 upwardly without tearing or detaching it from the disk 117. In this way any text or graphics material printed or otherwise applied to the label 110 remains intact.

Referring now to FIGS. 25 and 26, a further embodiment of an optical disk 120 is shown wherein a disk body 121 has a hole 122 covered by an integrally-molded, very thin web 124 that serves as a substrate which can be silk-screened or otherwise provided with a label. As distinct from the disk 55 shown in FIG. 9, the web 124 is solid. According to one embodiment of the invention the web 124 is sufficiently thin and deformable that it can be deflected upwardly from the surrounding annular edge of the disk body 121 by which it is integrally-formed without breaking to a degree sufficient to accommodate the spindle during rotation of the disk 120.

A label for an optical disk and method are described above. Various details of the invention may be changed without departing from its scope. Furthermore, the foregoing description of the preferred embodiment of the invention and the best mode for practicing the invention are provided for the purpose of illustration only and not for the purpose of limitation—the invention being defined by the claims.
