  • Abstract
    The performance of spindle motor system is crucial to HDD. The trend of ultrahigh ADD recording in the drive is bringing challenges to the spindle motor system. The paper presents several ways to handle these challenges, which include the measures in electromagnetic structure, mechanical system, and power drive.
