A detent mechanism for securing the magnetic head of hard disk drive above a landing zone of a magnetic disk, when power to the disk drive is terminated. The detent mechanism includes a first detent which is attached to the actuator arm and a second detent that is mounted to the housing of the disk drive unit. The detents have a pair of teeth that become locked when the actuator arm rotates above the landing zone of the disk. The detents are constructed to be flexible enough, so that the teeth may be separated when power is supplied to the drive unit and the actuator arm is rotated away from the landing zone. |
