Abstract

PURPOSE:To attain satisfactory track following control by calculating and forecasting the balanced point position of a future step motor from a track position signal larger than the number of sectors of a data track provided to the outermost circumference of a disk, and a past position signal on the data track. CONSTITUTION:The track position signal larger than the number of sectors of the data track is recorded to the outside of the outermost circumference of a floppy disk 19. At first, the following control is executed in the outermost track and a track position error signal of a step motor 18, which is detected by a servo pattern detector 15 and a position error signal generator 16, is stored. Next, a following control mode in the data track is obtained. At such a time, a prescribed coefficient is multiplied to the above mentioned error signal and the track position error signal obtained in the data track in the past with time and added, and the future position error signal is calculated. Thus, when the following control is executed with using this signal, the degradation of the following control due to the decreasing of the number of samples can be prevented.
