Abstract
The concept of the disclosed invention is to interleave a data bit stream with itself in such a way that the respective interleaved portions are displaced from each other, within the medium, by a distance corresponding to at least the statistical maximum size of the defects. In the event, during playback, that a dropout should occur, that dropout--inherently--must affect both interleaved portions. Therefore, by continuously delaying timewise one such interleaved playback portion relative to the other for a time sufficient to bring the two playback portions into sync with each other, the original bit stream may be reconstituted by toggling back and forth between the two playback portions each time a dropout is detected in either playback portion.
