Abstract
In a multi-disk system, index equivalent signals from a plurality of disk units are identified, and an average phase value of each disk unit is calculated from the identified signals so that each disk unit can synchronize its rotation phase according to the result of calculation and the index signal thereof in order to eliminate the need for a master index for the synchronization of rotation speed and rotation phase.
