of material originating from both the layer 13 and the layer 14 the diameter of the formed holes is 1 2 um the recorded information may be read either in reflection or transmission from the air or via the substrate plate 8 in the recording element shown in cross section in fig4 two parallel arranged glass plates 17 and 18 each have a thickness of 1 mm these glass substrate plates are connected together by a cylindrical central spacer 19 manufactured from metal as well as an annular metal second spacer 20 the spacers 19 and 20 adhere to plates 17 18 and seal the space between the plates in an airtight manner from the surroundings the opposing surfaces of plates 17 and 18 are provided between the spacers 19 and 20 with u v light cured acrylate lacquer layers 21 and 22 respectively optically readable servo tracks 23 and 24 respectively are provided in the surface of the lacquer layers 21 and 22 lacquer layers 21 and 22 have a thickness of roughly 1 um and are covered with dye containing recording layers 25 and 26 respectively as described in examples 1 3 upon recording information the servo track is read with weak laser light in reflection via the substrate plate and on the basis of the servo data holes 27 and 28 respectively are formed in the recording layer by means of pulsated laser light which is focused on the recording layers 25 and 26 respectively the laser has a power of 7 mw on the recorded layer and a pulse time of 5 10 7 sec the holes 27 and 28 corresponding to the information have.
