ABSTRACT:
A data writing device for preventing a phase-change optical disc from deteriorating due to repeated writing and for preventing the rewritable number of times of the disc from decreasing. The device writes data including synchronization frames to the disc. Each synchronization frame includes a primary or secondary synchronization signal. A comparator compares a first accumulated DSV for specifying the data including the primary synchronization signal for the synchronization frame with a second accumulated DSV for specifying the recording data including the secondary synchronization signal for the synchronization frame and generates a first selection signal based on the comparison. An inverter randomly inverts the first selection signal to generate a second selection signal. A selection circuit receives the primary and secondary synchronization signals and outputs the primary or secondary synchronization signal in response to the second selection signal.
