A carriage driving apparatus for a disk player in which the stability and responsiveness of the feedback loop are improved. The carriage driving apparatus includes a driving coil disposed in a magnetic path extending in the radial direction of a disk for driving a carriage carrying a pickup in the forward/backward direction of the magnetic path in response to a driving current, a velocity detecting coil disposed in the magnetic path for generating a velocity detection output in accordance with changes in flux, and velocity detection correcting device, including a leakage correction equalizer and arithmetic circuit, for correcting the detection output of the velocity detecting coil in accordance with the frequency and intensity of the driving current flowing in the driving coil.
