The invention relates to an apparatus () enabled to provide power to a powered device () via a wired data link (). The apparatus () is configured to provide the power to the powered device () in accordance with a configuration determined based on at least one parameter transmitted by the powered device () via the wired data link () in a power cycle. Further, the apparatus () comprises a memory () for storing an information about the configuration and a controller () for controlling the apparatus () on the basis of the stored information to provide power in accordance with the same configuration to the powered device () in a subsequent power cycle after a power outage. Moreover, the invention relates to a method for operating the apparatus ().

Rapid resumption of a power supply via a data link after power outage

The invention relates to methods and devices for forming marks and lands by applying a radiation beam () to a recording surface () of an optical record carrier (). Recording strategies are proposed for recording information at high recording speeds. An intermediate power level (P, P) is introduced in between the bottom power level (P) and the write power level (P), its value being dependent on the length of the preceding land (). A raised write power level (P, P) is also proposed, its value being dependent on the length of the mark to be recorded ().
