Printing method for disc-shaped information carriers

A method for providing a disc-shaped information carrier with label information in the form of graphics and/or characters, said information carrier having a first layer for receiving the label information and a second layer in which optical readable information is included, the method comprising:

• preparing the label information by means of a data processing system;
• transferring the label information from said data processing system to a printer for processing, said printer having a printing head for printing;
• and
• printing the label information directly on at least a part of said first layer;
• wherein during printing, said printing head and said information carrier are moved relative to each other on lines which extend perpendicularly to each other.

A method for providing a disc-shaped information carrier with label information in the form of graphics and/or characters, said information carrier having at least a first layer for receiving the label information and a second layer in which optically readable information is included, the method comprising:

• preparing the label information by means of a data processing system;
• transferring the label information from said data processing system to a printer for processing;
• and
• printing the label information directly on at least a part of said first layer;
• wherein in printing the label information on the record carrier, a laser-sensitive exposure cylinder is illuminated by a laser and exposed areas are wetted by an ink-supply means in conformity with the label information, ink is transferred from said exposure cylinder to a printing cylinder in conformity with the label information, and said ink is transferred from said printing cylinder to said information carrier.

An apparatus for providing a disc-shaped information carrier with label information in the form of graphics and/or characters, said information carrier having at least a first layer for receiving the label information and a second layer in which optically readable information is included, the apparatus comprising:

• a printer having a printing head for printing the label information directly on at least a part of said first layer;
• and
• a data processing system for preparing and transferring the label information to said printer for processing;
• wherein during printing, said printing head is moved radially relative to said information carrier and said information carrier is rotated.
