ABSTRACT:
A disk drive recording device comprises at least two platters for storing magnetic recording data and a spindle motor rotating at high speed for mounting the platters. The disk drive is assembled by using pushing devices to push the platters toward the center of the spindle motor in respective directions to bring a portion of an inside circumference of a concentric center hole of each of the platters in contact with an outer circumference of the spindle motor so that the center of gravity of each platter coincides with a center axis of the spindle motor.
