The present invention relates to determining at least one write strategy, using a write strategy model comprising first and second parameters, for recording data on a recording medium comprising, providing at least one set of randomised first parameters, (102, step 202), writing at least one test data, 104, pattern by using said at least one set of first randomised first parameters, (102), (106, step 204), reading the recorded test data pattern, (108, step 206) and calculating a set of second parameters, (114),(112, step 208), based on said read test data pattern (110) and the at least one set of first randomised parameters, (102). From the calculated set of second parameters, (114) and the real data to be recorded, 118, sets of first parameters (120) are calculated, (step 210). The real data (118) are recorded (122, step 212) by using the chosen write strategy model.

A method and a corresponding apparatus for recording an information on a recordable optical record carrier (2) by irradiation of a light beam through an optical system (3-7) onto said record carrier (2) for forming marks and lands representing said information along an information recording direction (t), obtains a higher recording density, and thus higher data capacity, by using astigmatism for influencing the light beam from the light source (8) to the record carrier (2) during recording of information so as to obtain a light beam having a substantially oval spot profile having a shorter axis in the information recording direction (t), i.e., the tangential direction for an optical disc, compared to the direction (r) orthogonal thereto, i.e., the radial direction.

A multi-stack optical data storage medium for rewritable recording by a focused laser-light beam, the medium having a substrate with deposited on aside thereof: a first recording stack comprising a phase-change type recording layer at least one further recording stack comprising a phase-change type recording layer, a transparent spacer layer adjacent each further recording stack. The further recording stack is sufficiently transmissive to ensure proper sensitivity for reading and recording in the first recording stack. For this purpose, at least one indium tin oxide layer is present in at least one of the further recording stacks. The indium tin oxide layer further ensures proper cooling behavior of the recording layer of the further recording stack in order to obtain sufficient recording performance in the farther recording stack.

The invention relates to the on-line analysis of meta-data that is received together with a video signal. This analysis results in an adaptation of the lighting surrounding the presentation device (110). One or more characteristics of the meta-data are filtered out and translated into lighting settings of one or more light elements (102, 104, 106, 108), which in turn can contain one or more light sources.
