RECORDING OR/AND PLAY-BACK DEVICE OF OPTICAL TAPE

摘要

The system separately has a head for recording an information by scanning a regular heat energy laser, which is modulated in accordance with the information, on the optical tape, and the head for playing back the information to detect the reflect light modulated in accordance with the recorded information by scanning the lower energy laser. The head for playing back particularly has an optical erasing function. The system lowers mechanical noise and electric power loss.
