ABSTRACT:
A video index search control circuit for a cassette recorder utilizing 8 mm recording tape and performing tracking in response to four tracking signals of differing frequencies includes a tracking controller for controlling tracking in accordance with the tracking signals and a head for selectively recording and reproducing the tracking frequencies, a video signal and audio signal, an amplifier for varying amplitude of said tracking signals generated by said tracking controller to produce high amplitude tracking signals and a video index search system signal detector for sensing the high amplitude tracking signals and for producing a high voltage signal indicating the presence of the high amplitude tracking signals. A method for controlling a video index search function is also disclosed.
