Abstract
An editing apparatus for use with a tape-form recording medium is provided in which, according to a positioning signal and a tracking pilot signal multiplex-recorded into the first recording area of each track of the recording medium which consists of a plurality of recording areas separated from each other by gaps, a pilot sampling signal for determining the timing of sampling and an editing timing signal for determining the recording location in a desired recording area following the first recording area are produced. After the tracking control is executed through sampling the tracking pilot signals from adjacent tracks at the timing of the pilot sampling signal, a data signal is recorded into the desired recording area after the first recording area according to the editing timing signal.
