Abstract

A disk drive system and method for implementing the same. The disk drive system of the present invention includes a discoid medium which rotates about its rotation axis and stores data. An actuator includes a head for reading or writing data from or in the discoid medium as it bidirectionally rotates about its bidirectional-rotation axis. The disk drive system further includes a housing which has a predetermined width and houses the discoid medium and the actuator, wherein the rotation axis of the discoid medium and the bidirectional-rotation axis of the actuator are arranged at the center in the width direction of the housing, and wherein size of the discoid medium is smaller than that of a discoid medium corresponding to a form factor of the housing.

Claims (4)

1. A hard disk drive, comprising:

a magnetic disk having a diameter of 60 mm or less to magnetically store data, wherein said magnetic disk is set to a spindle so as to be rotatable;

a rotary actuator having a magnetic head for storing data in or reproducing data from said magnetic disk, and bidirectionally rotates about a pivot; and

an enclosure case of a 3.5″ form factor having a predetermined width to house said magnetic disk and said rotary actuator, wherein said spindle and said pivot are set to the width-directional center of said enclosure case.
