Abstract

Abstract An apparatus and method of recording and reproducing information on a recording medium including recording at least a first track of encoded data information and with the data information occurring at first regular intervals along the recording medium and recording a second track of clock information and with the clock information occurring at second regular intervals along the recording medium and with the second regular intervals occurring no more than every other one of the first regular intervals. The encoded data information on the first track is reproduced and stored and with the reproduction and storage controlled in accordance with the reproduction of the clock information in the second track. The second track of clock information is reproduced by at least a pair of spaced sensors for successively reproducing the clock information along the second track and with the reproduction of the clock information successively alternating between the sensors and wherein the reproduction and storage of the encoded data information is controlled by the successive alternating reproduction by the pair of sensors so that each portion of the encoded data information occurring at the first regular intervals is not reproduced and stored until both sensors have alternately reproduced clock information.
