Arrangement for recording a video signal and a corresponding audio signal in slant tracks on a longitudinal magnetic record carrier, and record carrier obtained by means of the arrangement

Arrangement for recording a video signal and a corresponding audio signal in slant tracks on a longitudinal magnetic record carrier, the tracks each being built up of a clock run-in part, a track tone recording part, and an audio/video signal recording part, the arrangement comprising:

• an input terminal for receiving the audio and video signals;
• conversion means for converting the audio and video signals into a format in which the converted audio and video signals can be recorded on the record carrier;
• clock run-in signal generating means for generating a clock run-in signal;
• tracking tone signal generating means for generating a tracking tone signal;
• and
• signal combining means for combining the clock run-in signal, the tracking tone signal, and the converted audio and video signals, so as to enable the recording of said signals in the clock run-in part, the tracking tone recording part and the audio/video signal recording part, respectively, of a track;
• characterized in that the tracking tone signal for recording in each track comprises a concatenation of a number of packets, each packet including a sync block having a first or a second disparity and an identification block having a third or a fourth disparity, the disparity of the sync blocks and the identification blocks in the packets in the tracking tone recording part being chosen such that a running digital sum of the tracking tone signal varies as a relatively low frequency waveform compared to a bit frequency of the signal in the tracking tone recording part, the first and the second disparities having equal values but opposite polarities, the third and the fourth disparities having equal values but opposite polarities, the identification blocks in the subsequent packets in the tracking tone recording part in each of the tracks each include a first and a second binary count value, the second binary count value being a binary inverted value of the first binary count value, the first binary count value relating to the sequence count number of a respective packet in a tracking tone recording part.
