Abstract

L'invention concerne un disque compact non circulaire, pouvant être monté sur un lecteur de disque compact informatique. Ce disque possède plusieurs marques de positionnement et des moyens de résistance au glissement. Les marques sont formées sur des positions, où le contour extérieur du creux de positionnement intérieur d'un plateau portant un disque rencontrent les côtés les plus longs du disque, tandis que le centre du disque est placé au centre du creux de positionnement. Les moyens de résistance au glissement sont situés dans une zone sans données de la surface inférieure du disque, et sont constitués d'un matériau résistant au glissement présentant un grand coefficient de friction. Ces moyens sont conçus de manière à empêcher le déplacement inopiné du disque sur le plateau. Les moyens de résistance au glissement présentent une forme rectangulaire longitudinale, mais peuvent également présenter une forme circulaire. Le disque compact de forme non circulaire possédant des marqueurs de positionnement et une résistance au glissement peut présenter la forme d'une carte de crédit rectangulaire, et peut être un CD-ROM capable de stocker uniquement des données de lecture, un CD-R capable d'enregistrer des données une seule fois, et un CD-RW capable de lire, d'écrire et d'effacer des données plusieurs fois.
