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 xe2x80x9cburnedxe2x80x9d 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 xe2x80x9cbusiness cardxe2x80x9d disk, which comprises a 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 disk""s 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 xe2x80x9cbusiness cardxe2x80x9d 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 xe2x80x9clabelxe2x80x9d, 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, other 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.
Therefore, it is an object of the invention to provide a label for an optical disk which permits text and/or graphics to be placed over the hole in the center of the optical disk.
It is another object of the invention to provide a label for an optical disk which permits text and/or graphics to be placed over the hole in the center of the optical disk without interfering with the utility of the hole.
It is another object of the invention to provide a means of permitting text and/or graphics to be placed over the hole in the center of an optical disk having a silk-screened label thereon.
It is another object of the invention to provide a means of permitting text and/or graphics to be placed over the hole in the center of an optical disk having a sheet label thereon.
These and other objects of the present invention are achieved in the preferred embodiments disclosed below by providing a label for an optical disk of the type having a hole therethrough for being positioned onto a rotatable spindle by which the optical disk is rotated. The label comprises a sheet having a size and shape for being positioned on and adhered to the optical disk and overlying the hole. The sheet includes a plurality of slits formed therein for being positioned in registration with the hole in the disk when the label is positioned on the disk and defining between the slits a plurality of adjacent sheet segments for normally residing in the plane of the sheet and being deformable from the plane of the sheet in response to an object being extended into the hole, whereby the plurality of sheet segments can be provided with visual material while not interfering with the utility of the hole in the disk.
