发明名称 Multilayer record carrier with shifted recording start and stop positions
摘要 The present invention relates to a multilayer record carrier, to a recording apparatus and to a method of recording on such a multilayer record carrier, and to a manufacturing method, wherein start and stop positions of recording areas at header portions (H) are shifted in a lower recording layer ( 8 ) by a predetermined distance (Delta) such that recording and reading in/from the lower layer ( 8 ) is not affected by a variation in the transmittivity of the upper layer ( 6 ) at the transitions between the recording areas (R) and the header portions. The shifting may be obtained by extending gap portions or adding mirror areas to the header portions (H).
