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 (Δ) such that recording and reading in/from the lower layer (8) is not affected by a variation in the transmissivity 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).
