PURPOSE:To form a plastic recorder which has a small shape and power consumption, easy modulation, and high frequency by providing a semiconductor and an optical fiber. CONSTITUTION:Impressed voltage and impressed pulse voltage are changed by a signal, the outputted light of a semiconductor laser is changed, and the output of the semiconductor laser which is changed by giving deflection simultaneously is shifted as a recording signal. Then, the recording of the signal is executed by contacting a plastic. Therefore, the high-density recording can be executed without using a lens system, etc., at all. Since the light can be passed through the air, it is not necessary to place a plastic film in the air, and the very simple operation is obtained. There is no need of the system such as vacuum air-discharge, and obtaining its small size is possible. Since an optical fiber is used, it can be combined with the plastic which is recording medium directly without passing through an optical system such as the lens, and the light can be transmitted easily up to the desired location. |
