MULTILAYER OPTICAL DISC HAVING A RECORDING STACK TYPE INDICATOR |
摘要 |
A multilayer record carrier of a writable type has a first recording layer (40) having a first recording stack (50,51) of a first type and a second recording layer (41) having a second recording stack (54,55) of a second type. The first and second recording stacks have different writing parameters. Each recording layer has a pre-formed recording control pattern that is readable via a laser beam for indicating the track. At least one recording control pattern comprises a recording stack type indicator for indicating the writing parameters of the second recording stack. A recording device has a control unit (20) for adjusting recording parameters in the device in dependence of the recording stack type indicator retrieved from the recording control pattern.
