Abstract: PURPOSE:To make recording points independently to the respective layers of multi- layered films and to improve recording density by forming the light absorptive layers of respective optical recording units in such a manner that the absorption polarization directions thereof differ from each other. CONSTITUTION:This optical recording medium is formed by laminating >=2 layers of the optical recording units each consisting of a heat insulating layer, light absorptive layer and optical recording layer on a substrate. The light absorptive layers thereof exhibit light absorption only to the linearly polarized light of the specific polarization direction and the absorption polarization directions of the light absorptive layers differ from each other. The focus of a laser beam is made coincident with the light absorptive layers of the respective optical recording unit layers and the polarization direction of the linearly polarized light is rotated so as to coincide with the light absorption directions of the respective absorptive layers. For example, the linearly polarized beam (semiconductor laser beam) of the high-density energy having the absorption wavelength of the 1st light absorptive layer 4 is condensed from the substrate side to the surface of the 1st light absorptive layer 4 in the stage of writing. The polarization direction of the light beam is made concident with the light polarization and absorption directions of the 1st light absorptive layer 4.

While the pawl 6 is opened inside since a cam follower 16b is pushed up by the cam 12b. An original 1 is stopped temporarily at positions of timing rolls 4a and 4b and the carried again when both pawls 5 and 6 reach with revolutions said prescribed positions. Thus the original 1 is pushed between the pawl 5 and a guide 24. Then the follower 16b is detached from the cam 12b and the pawl 6 presses the tip of the original 1 to the pawl 5. Then the drum 2 is revolved to reach the position where the original 1 is supported by the force of the spring 23. Thus a loading action is through with the original 1.
