Abstract
A disk drive head assembly enables adjustment of a center of gravity of the head assembly of a depopulation version, while suppressing an occurrence of a resonance frequency affecting the performance of the disk drive apparatus. The head assembly for the data storage media includes: magnetic heads for reading/writing data from/to the data storage media, arms to which the magnetic heads are attached, a pivot shaft holder for supporting the arms, a coil for a voice coil motor extended from the pivot shaft holder, and a counter weight provided at a predetermined position opposite to a coil for the voice coil motor with respect to the pivot shaft holder.
