摘要： A writable optical record carrier (100) comprising a plurality of recording layers LO,..., Ln-1 separated by a spacer material, each recording layer comprising an optimum power calibration area (101,111,121,131) having a first portion (102,112,122) with an average reflection value representative of a recorded layer and a second portion (113,123,133) with an average reflection value representative of an unrecorded layer, a method, and an apparatus for forming optimum power calibration areas on such a writable optical record carrier are presented. The optimum power calibration areas partially overlap such that the optimum power calibration areas of each pair of consecutive recording layers form a step, and the first portions of said plurality of recording layers have the form of a staircase. Each step formed by a pair of consecutive recording layers k, k+1 has a preferred minimum step size.

摘要： The present invention relates to a multi-stack optical data storage medium (10). The medium comprises a first substrate (1a) with present on a side thereof a first recording stack (13) named L 0 , a second substrate (1b) with present on a side thereof a second recording stack (12) named L 1 comprising a recordable type L 1 recording layer (4) having a thickness t RL1 and a complex refractive index n λ - i*k λ at a wavelength λ. A second reflective layer (6) is present adjacent the L 1 recording layer (4) at a side most remote from a radiation beam (20) entrance face (11) of the medium. The second recording stack L 1 (12) is present at a position closer to the entrance face (11) than the L 0 recording stack (13). A radiation beam transparent spacer layer (9) is sandwiched between the recording stacks (12, 13). In order to achieve compatibility with the DVD-9 ROM standard as far as reflection levels are concerned, the second reflective layer (6) mainly comprises the metal Cu and has a thickness t MLn selected from the range of 8 - 20 nm and the thickness t RL1 and k λ of the recordable L 1 recording layer (4) fulfils the formula t RL1 *k λ ≤ 8 nm.
