Abstract
The utility model discloses an 80mm ultrathin DVD compact disc, which comprises a DVD semi-slice and a holding part, wherein the thickness of the DVD semi-slice is 0.6mm and the diameter of the DVD semi-slice is 80mm; one side of the DVD semi-slice is provided with an information area having an outer diameter of 76mm and an inner diameter of 45.2mm; the holding part having a thickness of 1.2mm and a diameter of 33mm is concentrically arranged in the middle of the DVD semi-slice; and a through hole having a diameter of 15mm is arranged on the center of the holding part. Because of the DVD semi-slice having a thickness of 80mm and a diameter of 0.6mm, the information area arranged on one side of the DVD semi-slice and the holding part correspondingly arranged in the middle of the DVD semi-slice, the formed DVD compact disc has a greatly reduced thickness and is only half of the traditional DVD, is prevented from warping due to the diameter of 80mm, and can be used on DVD equipment.
