An optical tape duplicator (1) is disclosed for making multiple copies of recorded optical tape (2) by continuous contact recording. An information-bearing endless master tape (2) is brought into intimate contact with an optical tape (3) and passed through a recording zone (5) exposed to a beam of radiant energy (4) for recording information stored by the master tape (2) into the optical tape (3). The master tape (2) contains transmissive and non-transmissive portions that represent the information stored by the master tape (2). The optical tape (3) contains a recording surface (33) that is sensitive to the radiant beam of energy (4). The beam of radiant energy (4) passes through the transmissive portions of the master tape (2) while making contact with the optical tape (3) in the recording zone (5), causing information stored by the master tape (2) to be recorded in the recording surface (33) of the optical tape (3) as indicia (35) where the recording surface (33) was exposed to the beam of radiant energy (4). <MATH> |
