Abstract
Disclosed is an ultrathin compact disc, which overcomes defects of rather big size, complex manufacturing technique and high cost of production of a standard compact disc. The utility model is characterized in that the diameter of the disk is 120mm, and the thickness (6) is between 0.55mm and 0.85mm, and the disk has a central clamping region (7) with a rather big thickness, the thickness (8) of the central clamping region is bigger than the thickness (6) by 0.1-0.6mm, and the ultimate thickness is not more than 1.2mm.
Description
Affiliated technical field
The utility model relates to a kind of ultrathin CD.
Background technology
Present disc types mainly contains CD class DVD class, comprise CD, CD-ROM, CD-R, CD-RW, DVD-5, DVD-9, DVD-10, DVD-14, DVD-R, DVD-RW etc., the circular dimension of general employing standard, promptly all disc external diameters are necessary for 120mm or 80mm, internal diameter 15mm, thickness 1.2mm so just can meet the requirement of international standard.This just international standard is popularized CD, DVD disc, but its standard size big (external diameter 120mm, thickness 1.2mm).The Internet of blast development and miniature digital storage equipment a kind of low price of hand-held electronic equipment application requirements, that be easy to carry about with one come corresponding to the numerical information of explosive growth and the optical disc applications field that enlarges gradually.
Summary of the invention
Existing compact disk standards size is big in order to overcome, complex process, the shortcoming that is unfavorable for carrying and uses in small sized applications, the utility model provides a kind of ultrathin CD, enough information stores spaces can be provided, satisfy the needs of existing optical disc applications, and reduce production costs by reducing materials and simplifying technology.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of ultrathin CD is provided, and is respectively center pit (1), center no datat part (2), spacing ring (3), data recorded area (4) and outer (5) from inside to outside.Cd diameter is the 120mm of standard, and wherein the thickness of the part except that core (6) scope is from 0.55mm to 0.85mm.For with existing player and driver compatibility, increase the center intensity of ultra-thin CD simultaneously, center no datat part (2) has corresponding clamping zone (7), the thickness (8) of clamping zone (7) is greater than the CD other parts, the diameter of clamping zone should be less than spacing ring (3), the thickness of clamping zone (8) the relatively thickness (6) of other parts increases 0.1-0.6mm, but finally is no more than 1.2mm.Data recording of the present utility model district (4) adopts existing DVD or EVD technology canned data.Can keep like this and the compatibility of existing DVD, EVD product.
The beneficial effects of the utility model are, contrast existing CD, ultrathin CD have size little, in light weight, be easy to carry, memory capacity is approaching, production cost saving.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a radially schematic appearance of the present utility model.
Fig. 2 is the tangential sectional view of ultrathin CD.
1. center pits among the figure, 2. center no datat part, 3. spacing ring, 4. data recorded area, 5. outer, 6. thickness, 7. clamping zone, the 8. thickness of clamping zone.
Embodiment
During concrete enforcement, the radial position of the center pit in Fig. 1, Fig. 2 (1), center no datat part (2), spacing ring (3), data recorded area (4) and outer (5) all meets the standard of DVD and EVD, thickness (6) can be selected between 0.55mm-0.85mm, and center clamping zone thickness (8) can be selected between 0.65mm-1.2mm.
Claims (4)
1. ultrathin CD, it is characterized in that the CD profile diameter is 120 millimeters, thickness except that core (6) is in 0.55-0.85 millimeter scope, and has the bigger center clamping zone (7) of thickness, center clamping zone thickness (8) relatively other parts thickness (6) increases the 0.1-0.6 millimeter, finally is no more than 1.2 millimeters.
2. according to the ultrathin CD described in the claim 1, it is characterized in that the information in the information stores zone (4) is with the DVD format record.
3. according to the ultrathin CD described in the claim 1, it is characterized in that the information in the information stores zone (4) is with the EVD format record.
4. according to the ultrathin CD described in the claim 1, it is characterized in that the information in the information stores zone (4) is with other related pattern records.
