40µm system
Analogue speed
40µm system - 20m/s (−3dB)
20µm system - 10m/s (−3dB)
Angular speed
Angular speed depends on disc optical diameter – use the following equation to convert to rev/min:
Angular speed (rev/min) =
V × 1000 × 60
p D
where V = maximum linear speed (m/s) and D = optical diameter (mm)
