A tracking-error correcting system for use in apparatus of the type wherein signal information is recorded in parallel tracks on a record medium. The correcting system is useful for correcting deviations between the scanning path of a transducer which scans the record medium and the parallel tracks. A ramp signal generator generates a periodic ramp signal of substantially constant amplitude and having a duration which is equal to at least a portion of the time required for the transducer to traverse its scanning path. The level of the ramp signal is changed for successive scans of the record medium. An adjustable transducer support is provided to support the transducer in scanning relation to the record medium and is operative to displace the transducer transversely with respect to a parallel track in response to a drive signal applied thereto so as to align the scanning path of the transducer coincidentally with the parallel track. The ramp signal of changing level is used to produce the drive signal. The level of the ramp signal no longer is changed when the scanning path of the transducer is detected to substantially coincide with a parallel track.
