Abstract: A recording/reproducing apparatus for an optical recording card is disclosed, which comprises an optical recording card (10) provided with an optical recording medium (11), a recording light source (5) for recording an information signal on the recording medium (11), a reproduction light source (1) for reproducing the information signal recorded on the recording medium (11) and a line sensor (15) for reading out the information recorded on the recording medium (11) from the light beam reflected from the recording medium (11). A light path of a light beam emitted from the recording light source (5), a light path of a light beam emitted from the reproduction light source (1), and a light path of the light beam reflected by the recording medium (11) are independent of one another.
