Abstract (en)

[origin: WO0042605A1] A noncircular-shaped compact disc mountable in any computer compact disc drive is disclosed. The disc has two or more positioning marks and sliding-resistance means. The marks are formed on the positions, at which the exterior contour of the inside positioning depression of a disc conveying deck meets the long sides of the disc while the center of the disc is positioned at the center of the positioning depression. The sliding-resistance means is provided within the data-free area of the bottom surface of the disc, and is made of a sliding-resistance material having a large coefficient of friction. The means is adapted for preventing the disc from unexpectedly moving on the deck. The sliding-resistance means may have a longitudinal rectangular shape. The sliding-resistance means may have a circular shape. The noncircular-shaped compact disc having positioning markers and sliding-resistance may have a rectangular credit card shape. The noncircular-shaped compact disc having positioning markers and sliding-resistance may be any one of a CD-ROM capable of storing read-only data, a CD-R capable of recording data only once, and a CD-RW capable of reading, writing and erasing data many times.
