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 rotatable carousel on which said plurality of disk stacks are fixed;
- 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, and
- an 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 said plurality of disk stacks.
