With the continuing upgrading of CD cutting technology, any custom-designed shape can be manufactured as long as the shape is perfectly symmetrical and at least three points of the shape meet the inside of the 120 or 80 mm CD drive track. The production lead time is longer than for standard shaped CDs and the data capacity for these specifically shaped CDs is solely dependent upon the diameter of the closest cutting point toward the CD hub ring. In recent years, digital information has been successfully stored and played with even higher CD drive speeds. To develop User Type cards, please consult with a sales representative before production.
