Abstract: Timing signals are generated in a prescribed time duration after signal edges of data signals. Integrated data signals, rather than the data signals themselves, are sampled with these timing signals. First, data contained in the data signals is recovered from the sampling signals generated by the sampling. Noise signals are eliminated by integration of the data signals, and the data is recovered with greater protection against disturbance. The integration can occur with analog or digital components, and it is possible to provide the sampling of the data signals in addition to the sampling of the integrated data signals in order, when warranted, to recover the data from the data signals, or from the integrated data signals, dependent on the respective disturbances.

Abstract: In a system for controlling the motion of a magnetic head in a magnetic tape recorder, in order to achieve an optimally uniform wear of the magnetic head at a side thereof facing the magnetic tape, the magnetic head is constantly moved back and forth during a movement of the magnetic tape during at least one of the modes fast forward and rewind. In magnetic tape recorders wherein the magnetic head is positionable to various tracks of the magnetic tape transversely relative to the moving direction of the magnetic tape, wear on the head can occur at least partially during fast fast forward and rewinding modes. By moving the head during fast forward or rewind, the magnetic head is less heavily worn and the edges of the magnetic tape are not damaged by undesirable depressions in the head.
