ABSTRACT:
A pickup device for compensating for jitter by driving a scanning needle in the direction of a record track on a disc comprises a resiliently held support which supports a cantilever having the scanning needle mounted thereon and a permanent magnet mounted at an end thereof, and a driver to which a drive current is supplied to generate a magnetic field to be acted on the permanent magnet. A drive force created by the action of the magnetic field is in parallel to a surface of the disc so that the scanning needle is driven in parallel to the surface of the disc.
