<p>The present invention relates to a multi-stack optical information carrier for recording information by means of a laser beam, said optical information carrier comprising:-a substrate layer (S),-at least two recording stacks (L 1, L 2 ), each comprising a recording layer (P 1 , P 2 ), at least one heat sink layer (H 1 -H 4 ) and dielectric layers ( 1 ) between said recording layer (P 1, P 2 ) and said at least one heat sink layer (H 1 -H 4 ),-at least one spacer layer (R) separating the at least two recording stacks (L 1, L 2 ), and-a cover layer (C). In order to improve the sensitivity during writing, preferably in the first recording stack (L 1 ), it is proposed according to the present invention that at least one recording stack (L 1, L 2 ) further comprises at least one thermochromic layer (T 1, T 2, T 3 ) having temperature-dependent optical characteristics for improving the sensitivity of at least one of said recording stacks (L 1 ) during recording.</p> |
