Abstract
Method and arrangement for controlling the data stream in a vibration-resistant playback device. In vibration-resistant playback devices, it is known to write the data to a buffer memory continually at a doubled rate and to read out the said data at a normal data rate. If no vibrations occur, artificial returns must be effected. This leads to an increased power consumption. The present invention enables a reading rate which can be adapted to the averaging of the periods of time when the information medium can and cannot be read. In order to enable processing of the data stream with such a variable reading rate, reading from a memory is switched over between a normal and doubled data rates and the processing stages are likewise correspondingly switched over. As a result, only information data is stored in a downstream buffer memory, so that a lower capacity is sufficient or, with the existing capacity, a longer time span can be bridged during which no data can be read.
