Abstract: Apparatus for recovering signals read back from a recording medium at different relative recording medium speeds have speed-switchable equipment for equalizing readback signals over frequency bands having different peak to-bandedge roll-off regions for different relative recording medium speeds. High-frequency equalization means in the speed-switchable equipment equalize readback signals in the peak-to-bandedge roll-off regions by providing speed-switchable frequency peaking characteristics and speed-switchable cut-off frequency characteristics and in company with each other shift the frequency peaking characteristics and cut-off frequency characteristics to the different peak-to-bandedge roll-off regions for different relative recording medium speeds.
