发明名称 Tw-sided, light-readable information recording disc stacks and methods of making same
摘要 Recording media made up of two discs bonded together back to back have one disc on which programming information is recorded in light-readable form (generally similar to conventional CDs or CD-ROMs) and a second disc bearing visible indicia regarding the recording media. At least some of the visible indicia on the second disc are generic (i.e., are not specific to the particular programming on the other disc). These generic visible indicia are preferably formed on the second disc prior to the bonding of the two discs together. Additional visible indicia that are specific to the particular programming on the other disc may be added to the second disc. The visible indicia may be provided in several ways such as by "pit art", thermal branding, laser scribing, printing, labelling, etc. The second disc may also contain some recorded, generic, light-readable information such as "Wrong side -- turn disc over." <IMAGE>
