摘要:
An editing apparatus is for use with a tape-form recording medium in which a tracking pilot signal and several synchronizing blocks each of which contains a synchronizing signal, a synchronizing signal number and a recording mode data are multiplex-recorded into a first recording area of each track which has a plurality of recording areas. Using the synchronizing signal and the synchronizing signal number, a pilot sampling signal for determining the timing of sampling the pilot signal and an editing timing signal for determining the recording location in a desired recording area following the first recording area are produced. Using the recording mode data, the discrimination of the current recording mode is carried out. After the tracking control is executed through sampling the tracking pilot signals from adjacent tracks at 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.
