Servo technology was used to position the heads.Servo information only was written on a specified surface of the stacked discs.Instead of writing user data on this surface,servo information was continuously read in order to position the heads.When the position was determined,reading or writing took place as this also made it possible to determine the positions of the other heads on the same cylinder.This technology is called the dedicated servo method.
