ABSTRACT:
An 8 mm image recording/reproducing apparatus is provided which is capable of searching for information recorded on a video tape based on signals recorded on a track of the video tape. Furthermore, the apparatus is capable of performing tracking control in accordance with reference pilot signals. The apparatus contains a controller, a pilot signal generator, a search reference signal generator, a recording/reproducing section, and an index signal separator. The controller generates a mode selection signal and a pilot selection signal, and the mode selection signal indicates whether the apparatus is operating in an index signal record mode or an index signal separation mode. The pilot signal generator sequentially and cyclically generates the reference pilot signals. The search reference signal generator generates an index signal and an index separation reference signal based on at least is one of the mode selection signal and the pilot selection signal. The recorder/reproducer records the reference pilot signals output from the pilot signal generator and the index signal on the video tape and reproduces a previously recorded index signal and at least a second signal from the video tape. Finally, the index signal separator separates the previously recorded index signal from the at least a second signal. Accordingly, the present invention is capable of performing high-speed search operations without adversely affecting the compatibility of a conventional 8 mm format.
