ABSTRACT:
Apparatus and method are disclosed for use in replicating information from a master record carrier, such as a videodisc, onto a replicate material in web form. In a preferred embodiment, the disclosed replication apparatus comprises supply, exposure and takeup chambers. A web cleaning device in the supply chamber cleans the replicate material of foreign particles. In the exposure chamber, the replicate material and a master record carrier are brought into close contact in order to make a contact print exposure. The exposed replicate material is stored in the takeup chamber. One or more sealport devices are provided to maintain certain vacuum conditions in the various chambers of the replication apparatus (1) to degas the replicate material of moisture, (2) to facilitate removal of foreign particles from the replicate material, (3) to facilitate close and uniform contact between the master record carrier and replicate material during the contact print exposure, and (4) to allow exposed replicate material to be removed from the takeup chamber without substantially affecting the vacuum conditions in the rest of the replication machine.
