Hard disk drive having multiple movable disk stacks on a guide rail

摘要

A lower cost per unit of storage hard disk drive (HDD) includes multiple disk stacks movably coupled to a guide rail and a head stack assembly (HSA) for accessing the magnetic-recording disks of each of the multiple disk stacks. A disk stack feeding mechanism may be implemented to move each of the disk stacks along the guide rail, and a positioning mechanism may be implemented to align and to temporarily fix a disk stack relative to an HSA. An internal filtering system may also be implemented for keeping contamination-free a compartment in which the disk stacks and HSA are operational.

主权项

1. A hard disk drive, comprising:
a plurality of disk stacks, each disk stack comprising one or more magnetic-recording disk rotatably mounted on a spindle; a guide rail on which said plurality of disk stacks are movably coupled; and a head stack assembly, comprising:
a head slider comprising a magnetic read/write head for reading data from and writing data to one or more magnetic-recording disk,a flexure, to which said head slider is coupled,an actuator arm, to which said flexure is coupled, andan actuator, to which said actuator arm is coupled, said actuator configured to move said head slider to access portions of said one or more magnetic-recording disk of each of the plurality of disk stacks.
