Abstract: PROBLEM TO BE SOLVED: To provide a balance correction device and correction method capable of surely and efficiently correcting dynamic balance and a disk assembling method. SOLUTION: A balance correction device 20' is constituted as follows. To a hard disk drive 10, in which a disk 1 and a spindle 2 are assembled on a base 4, an acceleration applied from an actuator 23 is worked to the tip 2a the spindle 2 by way of a holder plate 26' in one acceleration applying mechanism 22A and the acceleration applied from the actuator 23 works on the base part 2b of the spindle 2 by way of the base 4 in an acceleration applying mechanism 22B.
