Definitions

  • the present invention relates to an apparatus and a method for coating an optically readable data carrier, and to an optically readable data carrier.
  • Optical media such as B. CD's, as well as methods and devices for producing the same are well known in the art.
  • Such data carriers generally have a data-carrying surface which must be protected against environmental conditions.
  • a hardening lacquer was used, which was applied in a central area to the rapidly rotating data carrier in order to flow outwards by the centrifugal force and to form an essentially uniform layer on the CD.
  • the data carrier must be rotated at a high speed in order to generate sufficient centrifugal forces for an even distribution of the lacquer on the surface to be protected. This process involves the risk of damage to the data carrier.
  • excess paint is thrown off the data carrier in this method, which subsequently has to be disposed of in a complex manner.
  • EP-A-0 855 703 also discloses a method for gluing two essentially identical disk-shaped substrates of a data carrier with a double-sided adhesive film.
  • the present invention is based on the object of providing a simplified and inexpensive method for coating an optically readable data carrier and a data carrier produced in this way.
  • This object is achieved in a method for coating an optically readable data carrier in that a one-sided adhesive, transparent adhesive film is applied to a surface of the data carrier to be protected.
  • the use of an adhesive film has the advantage that the above-mentioned centrifuging process for coating the data carrier with a lacquer is omitted and no lacquer residues which have to be disposed of in a complex manner are thrown off.
  • the adhesive film also provides a simple and inexpensive solution for coating a data carrier.
  • the adhesive film is removed from a carrier film during or after being applied to the data carrier.
  • the backing film has the advantage that the film is protected from being applied to the data carrier and gives the adhesive film sufficient stability for transport.
  • a protective film is preferably removed from the adhesive film before the adhesive film is applied to the data carrier and protects the one-sided adhesive surface of the adhesive film from contamination and damage prior to the application process.
  • the shape and size of the adhesive film corresponds to the surface of the data medium to be protected, in order to cover it completely.
  • sections of the adhesive film corresponding to the shape and size of the data carrier are advantageously punched out on the carrier film.
  • the adhesive film is preferably applied centered on the surface of the data carrier to be protected, in order to ensure a uniform coating of all areas of the data carrier.
  • the adhesive film and the data carrier are preferably aligned with one another before application.
  • the adhesive film is applied to the data carrier by means of a rotating pressure roller during the application pressed, which ensures a secure contact between the adhesive film and the data carrier.
  • the contact pressure of the pressure roller is preferably controlled in order to achieve an optimal adhesive effect on the surface of the data carrier.
  • the adhesive film is preferably held at a predetermined angle to the surface of the data carrier before being pressed on by the pressure roller, in order to keep the adhesive film at a distance from the data carrier and to ensure controlled pressing only in the area of the pressure roller. This ensures that air pockets between the adhesive film and the surface of the data carrier are avoided.
  • the data carrier and the pressure roller are moved relative to one another in order to enable the adhesive film to be applied progressively to the surface of the data carrier.
  • the data carrier is moved linearly past the pressure roller, and the pressure roller is advantageously rotated synchronously with the movement of the data carrier in order to continuously press the adhesive film onto the data carrier.
  • the adhesive film is cured after being applied to the optical data carrier in order to provide increased strength and thus improved protection of the optical data carrier.
  • the adhesive film is preferably cured by thermal treatment and / or pressure and / or time.
  • the adhesive film is advantageously cured by UV radiation.
  • a transparent protective layer in particular a so-called PC tape, is preferably applied to the side of the adhesive film that is not glued to the data carrier.
  • the object on which the invention is based is also achieved by a device for coating an optically readable data carrier with a lamina. Removal station for applying a one-sided adhesive, transparent adhesive film to a surface of the data medium to be protected.
  • an optically readable data carrier with a transparent protective layer in which the protective layer is a one-sided adhesive film.
  • the protective layer is a one-sided adhesive film.
  • the data carrier is arranged in a protective housing which surrounds the data carrier.
  • Figure 1 is a schematic representation of an apparatus for producing optical data carriers according to the invention.
  • Fig. 2 is a schematic view of parts of a laminating station according to the present invention.
  • FIG. 3 is a side view of an alternative embodiment of a laminating station according to the invention.
  • Fig. 4 is a schematic side view of an alternative adhesive film.
  • FIG. 1 shows a device 1 for producing an optical data carrier with at least one surface to be protected.
  • the device has a feed unit 3 for feeding an optical data carrier, such as a CD or a DVR.
  • an optical data carrier such as a CD or a DVR.
