  • Publication number: 20240096357
    Abstract: According to one embodiment, a disk device includes a rotatable magnetic disk, an actuator which supports and moves a head, a ramp which holds the head at an unloaded position, a motor which rotates the magnetic disk, and a controller which performs a load operation and a seek operation. When a radial travel speed of the head during the load operation is referred to as Vr1, a circumferential travel speed of the head is referred to as Vt1, a radial travel speed of the head during the seek operation is referred to as Vrs, and a circumferential travel speed is referred to as Vts, the controller controls at least one of the radial travel speed of the head and number of revolutions of the magnetic disk to satisfy a relationship (Vr1/Vt1)<(Vrs/Vts).

  • Publication number: 20090190260
    Abstract: A head slider is mounted at the mounting area on a plate-shaped gimbal in a head suspension. A swelling is formed on the load beam. A viscoelastic body is interposed between the load beam and the gimbal. The back surface of the gimbal is received on the swelling. The head slider on the gimbal is allowed to change its attitude on the swelling. When the gimbal is received on the viscoelastic body, the viscoelastic body serves to suppress the vibration of the gimbal, namely the head slider.
