A signal pickup device comprises a reproducing stylus for tracing a track on a rotary recording medium thereby to reproduce the information signal recorded thereon, a cantilever provided at a free distal end thereof with the reproducing stylus, means for supporting the cantilever so as to be rotatable about substantially proximal root end thereof and movable in an longitudinal direction thereof, coil means including at least two movable coils fixed to the support means, means for generating a control signal current in response to deviation of the tracing position of the reproducing stylus from a track to be traced, and supplying the control signal to the coils, and magnetic field forming means secured at a predetermined position of a main body of the device and adapted to apply to the coils a magnetic field in a direction parallel with the rotary recording medium. The coils undergo a motion due to a mutual interaction between the magnetic field and the current flowing therethrough, whereby the reproducing stylus is displaced by way of the cantilever at least in the width of the track and is thereby tracking controlled.
