Abstract: A reproducing transducer, in an apparatus for reproducing an information signal recorded on a track on a rotary recording medium, comprises a reproducing tracing element for tracing the track on the rotary recording medium thereby to reproduce the information signal, a cantilever supported at a proximal end thereof by way of a damper and provided at a free distal end thereof with the reproducing tracing element, a mechanism for detecting any deviation of the tracing position of the reproducing tracing element from a proper tracing position relative to the track and generating a tracking control signal in response to the deviation. A unit supplies the current of the tracking control signal to the cantilever or an electric conductor secured to the cantilever, and a permanent magnet applies a magnetic field to the cantilever or the electric conductor.

Abstract: A recording and/or reproducing apparatus comprises a signal transducer in the form of a single recording and/or reproducing head. A single step-driving device intermittently steps the head from one track position to another track position on a rotating recording medium to read two separate and alternating sets of tracks. Stepping occurs during a vertical blanking period of a video signal. A synthesized synchronizing signal is generated to compensate for any deficiencies of the synchronizing signal, as originally recorded, and as played back within a reproduced video signal.
