Abstract
PURPOSE:To make it possible to easily reproduce a lot of captioned tapes in a short time, by making a tape which has recorded a signal in the uneven form a master tape, and pressing an unrecorded tape by use of the master tape. CONSTITUTION:An endless tape 2 is made to run by means of the tape run driving mechanism consisting of a capstan 7 and a pinch roller 8, and when it is running, the laser light is modulated and exposed by a signal which has modulated a video signal to FM, by use of, for example, a laser head as the recording head 6. When the tape 2 recorded by the laser light has been subjected to development and etching, it becomes the tape 2 which has been recorded in the uneven form. The first master tape is produced by plating the uneven surface of this tape 2, the second master tape is produced by plating said surface, and the third master tape 61 is produced by further performing the electric plating onto the surface. A signal reproducing endless tape can be obtained by closely sticking an unrecorded endless tape 71 onto said tape 61, and performing the reproduction by means of heating press, etc.
