スク装置のヘツドロード機構。[Claim for Utility Model Registration] When the head is loaded, the electromagnetic drive source is excited, the bail is pushed through the arm member and rotates against the spring, the head arm rotates and the magnetic head contacts the magnetic disk. , when the head is unloaded, the electromagnetic drive source is demagnetized, the bail is rotated in the opposite direction by the spring, and the head load arm has its arm portion locked to the bail and rotates in the opposite direction. In a head loading mechanism of a magnetic disk device configured such that the magnetic head moves away from the magnetic disk, when the electromagnetic drive source is energized and the magnetic head is in contact with the magnetic disk, the bail is moved. A head load mechanism for a magnetic disk device, comprising an adjustment mechanism capable of adjusting a position relative to the arm member.
