Abstract

An actuator rotation limiter mechanism for a multi-disk stack shared-actuator hard disk drive includes an actuator comb having protruding pins, wherein rotation of the actuator comb is controlled by contact between the pin and a magnet. limited by gravity. An enclosure base may include a curved slot in which the pin is disposed, wherein one end of the slot may correspond to an inner diameter of a head slider adjacent to a first disk stack, and an end of the slot may The other end may correspond to an inner diameter of the head slider close to a second disk stack adjacent to the first disk stack. The magnet may be disposed in or adjacent to the curved slot at an intermediate position, wherein the pin is held by the magnet on an inclined plane where the head slider rests between the disk stacks. at the corresponding location.

Description

technical field [0001] Embodiments of the invention may relate generally to magnetic recording devices, and more particularly to limiting actuator travel in multi-disk stack shared-actuator hard disk drives. Background technique [0002] A hard disk drive (HDD) is a non-volatile storage device that is housed in a protective enclosure and stores digitally encoded data on one or more circular platters with magnetic surfaces. When the HDD is in operation, each magnetic recording disk is spun rapidly by a central axis system. Reading from and writing to a magnetic recording disk is performed using a read-write head that is positioned at a specific location on the disk by an actuator. Read-write heads use magnetic fields to read data from and write data to the surface of a magnetic recording disk. The write head uses an electric current through a coil to generate a magnetic field. Electrical pulses are sent to the write head using different patterns of positive and negative cu...
