The forth (Part 4) of five laserdiscs issued covering the 1990 Formula One Grand Prix World Championship which was won by Ayrton Senna(FIA F-1 World Drivers Champion 1988 '90 & '91). Each disc had one "volume" to each side - ten "volumes" over the five discs issued. Being MULTI AUDIO you can lose the Japanese commentary by flicking between the R or L audio channels which leaves only the original music, car & ambient racetrack sounds. On side two (the full side covers the Japanese round at the Suzuka circuit) the analog tracks are CX encoded. The footage covers the three days of the "race weekend" with practice, qualifying, the race & more. This is the race where Ayrton Senna & Alain Prost ended their 1990 Championship battle at the first corner on the first lap. The last chapter of side 2 shows the full race from one camera, sped up & over in around 90 seconds. "Copyright 1990 Formula One Constructors Association"
