The present invention relates to a multi-stack optical information carrier for recording information by means of an optical beam, said optical information carrier comprising - a substrate layer (S), - at least two recording stacks each comprising a recording layer (P1-P7),- at least one spacer layer (R) separating the at least two recording stacks, and- a cover layer (C). In order to improve the sensitivity during writing it is proposed according to the present invention that the recording layers (P1-P7) include a thermochromic material having temperature-dependent optical characteristics for selectively improving the sensitivity of the addressed recording layer (P1-P7) during recording and/or read-out.
