Always remember that angular speed does not directly convert to linear speed, since the radius of movement needs to be taken into account. Another calc provides this calculation. For reference, vinyl records spin at 33, 45, and 78 rpm, and CD and DVDs spin at up to ~10,000 rpm. The world rotates at around 1 revolution per day!
