Abstract
A control unit, stores addresses of a write pointer of a buffer in the case of the last valid subcode information and starts with a synchronization byte following an interruption. The synchronization byte is provided for the synchronization of the data stream in the buffer, an item of address information which identifies the interruption location in the data stream, the starting point of the synchronization being formed by a valid subcode, the address information being used as a reference both for the location of the interruption on the information medium and for the last valid data in the buffer and the writing in the buffer. This is done so that uninterrupted reproduction of information is provided despite vibrations in the playback device.
