Abstract:
A method for recording input data in a data recording operation on a recording medium having a data recording region for recording the input data and a control data region for recording control data for said data recording region, said method comprising:identifying a non-silent recorded portion and a silent recorded portion of the input data recorded in the data recording region; measuring a time during which the signal level of the input data recorded in said data recording region is below a pre-set level; discontinuing the data recording operation when the measured time exceeds a pre-set time duration; after the data recording operation has been discontinued, recording control data in said control data region so as to separate the input data recorded in the data recording region into temporally former and temporally latter portions at a boundary portion beginning between the non-silent recorded portion and the silent recorded portion; and writing additional data over the input data that was recorded into the temporally latter portion after the boundary portion, so that the input data that was recorded into the temporally latter portion after the boundary portion is effectively deleted.
