摘要： An actuator latch apparatus for a disk drive, having a notch positioned at a first end portion of the swing arm, a latch lever rotatably installed in a base member, a first core provided on a second end portion of the swing arm, and a second core provided at a counterbalance of the latch lever. The first and second cores apply a torque to the swing arm and latch lever, respectively, in a first direction by a magnetic force of the magnet. The latch lever has a latch pivot, a latch arm provided at a first side of the latch pivot and having a hook to be caught by the notch when the actuator is locked, and the counterbalance provided on a second side of the latch pivot. The latch arm of the latch lever is elastically deformed when contacted by the swing arm during parking of the head.

摘要： A latch for securing an actuator arm of a hard disk drive. The latch has a catch portion that can engage a latch portion of the actuator arm. The latch also has a pusher portion and a crash stop portion that engage the actuator arm during movement into a latched position and prevent the latch from rebounding away from the arm. The pusher and crash stop portions eliminate the need for a separate crash stop in the disk drive. Eliminating the separate crash stop component reduces the complexity and cost for mass producing the disk drive.

摘要： A gimbal head assembly and an actuator having the same, the gimbal head assembly and the actuator being included in a hard disk drive (HDD). The actuator can include a swing arm rotatably installed on a base member, the head gimbal assembly elastically biasing a read/write head towards a surface of a disk, and a voice coil motor rotating the swing arm. The head gimbal assembly can include a load beam attached to the swing arm, a flexure attached to the load beam, a slider mounted on a slider mounting portion of the flexure and comprising a read/write head installed on the slider, and an air foil disposed in front of the slider and guiding air flow generated due to rotations of the disk along both sides of the slider. The air foil reduces turbulent air flow in the vicinity of the slider, thereby reducing oscillations of the slider due to the turbulent air flow
