| 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.
