Abstract
PURPOSE:To obtain the high output of a reproduced output and to execute a simultaneous monitor at the time of recording of an information signal by respectively and independently providing respective incoming light path from a light source for a recording and a light source for a reproducing to a recording medium and a reflected light path by the recording medium of the light from the light source for the reproducing. CONSTITUTION:The optical axis of a laser light for recording, which is emitted from a laser light source 1, and the optical axis of a light for reproducing, which is emitted from an emitting diode 5, are positioned on respective flat surfaces to be orthogonal. Thus, an incoming light path Lw from the light source 1 for the recording to an optical recording medium 11 of an optical card 10, an incoming light path Lri from the light source 5 for the reproducing to the recording medium 11 and a reflected light path Lro in which a light from the light source for the reproducing is reflected by the recording medium 11 are obtained with being mutually independent. Accordingly, the recording operation of the information signal and a reproducing operation can be simultaneously executed and namely, the simultaneous monitor can be executed at the recording time. The high output of the reproduced output by a CCD line sensor 15 and a highly speedy operation are obtained.
