Embodiment Construction

[0032] In one aspect, the present invention provides a novel disc data storage medium characterized by a data storage surface at the edge of the disc. This new edge data surface can be given pre-recorded data or can be used as a read / write data surface. Methods of making disc data storage media with edge track data surfaces and converting existing disc media to include data surfaces at the edge surfaces of the discs will now be described, as well as utilizing other advantages and methods of the present invention.

[0033] figure 1 The schematic shows a typical disk management system configured as a horizontally aligned disk media stack (2). Such stacks of disks are often arranged in a ring configuration. Access to surface information on discs (1), such as title labels (4) or barcode manufacturing information (5), is impeded by narrow gaps (6) between adjacent discs. The disks are usually spaced some distance apart and are supported by grooves or fingers (3). A disk medium...

Abstract

The present invention relates to disk data storage media including magnetic, magneto-optical and optical media such as CD-ROM, CD-RW, DVD, DVD-RAM, Mini-disks and other disk media. It provides for new disk media featuring a data storage surface on the edge of the disk. This novel edge track data surface may be marked, inscribed or recorded during manufacture or this new data surface may be created and utilized later. In addition, methods to manufacture, exploit and convert conventional disk media to that having an edge track data surface are taught herein.

Description

technical field [0001] The present invention relates to disc data storage media including magnetic, magneto-optical and optical media, such as CD-ROM, CD-RW, DVD, DVD-RAM, MiniDisc and other disc media. It provides a new disc data medium which features a data storage surface at the edge of the disc. Background technique [0002] Disk data storage media are ubiquitous in the computer and entertainment industries and exist in numerous variations. Disk media can be pre-recorded, recordable, or re-writable on one or both disk surfaces, whereas with optical disks, each of the two opposing disk surfaces can have a single layer or multiple layers for data storage. [0003] In addition to data, disc media often carry other information on the disc surface, such as titles, content, or manufacturing information in the form of labels, barcodes, marks, photographs, and the like. For example, US Patent No. 6,058,086 teaches a method of writing in areas of the outer surface of an optical...
