DUAL-SPEED OPTICAL RECORD CARRIER RECORDING APPARATUS
摘要
The present invention relates to an optical record carrier recording apparatus and method for recording data on a phase-change optical record carrier (55) storing a state information about the location of crystalline and non-crystalline areas of the record carrier (55). In order to provide the possibility to write with different writing speeds on the record carrier, writing means (54) for recording data on the record carrier (55) can be switched between different writing modes. The first writing mode is used if the recording apparatus (5) is in a high power mode, e.g. supplied with power from a mains power supply and if a crystalline (unwritten) area is available on the record carrier (55). If no crystalline area is available or if the recording apparatus (5) is in a low power mode, the second writing mode having a lower writing speed is preferably used.
