    摘要： A method, an optical record carrier and an apparatus for writing information to an optical record carrier include reading a write strategy from the optical record carrier which has at least two write strategies, and forming pits and lands by controlling a radiation source with the read write strategy. The method further includes determining which of the at least two write strategies is the most optimal one by reading an indication present on the optical record carrier. The most optimal write strategy is used to form the pits and the lands. If an apparatus for writing information to an optical record carrier is capable of applying two or more write strategies stored on the optical record carrier, then the apparatus reads the indication and applies the write strategy which is the most optimal one.

    摘要： The invention described is an apparatus for reproducing information from an information carrier (11) comprising: a waveform equalizer (6) for obtaining a corrected signal (S′) by performing a waveform equalization to a read signal (S), the waveform equalizer (6) having an amplifying element with a gain (K); and gain setting means (1) for reading a numerical gain setting stored on the information carrier (11) and setting the gain (K) of the amplifying element to a value related to the numerical gain setting. By reading the numerical gain setting from the information carrier, the apparatus is able to set the gain (K) of the waveform equalizer to the optimal value for suppressing noise and inter symbol interference. The equalizer can be followed by a limit equalizer, the gain of which can also be wave form read from the information carrier.

The optical record carrier recording method forms pits and lands by controlling a radiation source to direct a radiation beam onto a recording surface of an optical record carrier (11), the method comprises the steps of: reading a write strategy from the optical record carrier (11) which comprises at least two write strategies, and forming the pits and lands by controlling the radiation source with the read write strategy, wherein the method further comprises a step of determining which of the at least two write strategies is the most optimal one by reading an indication present on the optical record carrier (11), and wherein the method uses the most optimal write strategy to form the pits and the lands. If an apparatus for writing information to an optical record carrier (11) is capable of applying two or more write strategies stored on the optical record carrier, then the apparatus reads the indication and applies the write strategy which is the most optimal one.
