ABSTRACT:
A disk drive information storage device having a pair of disks for storing information, the storage device including a clamp for mounting disks on a hub, the clamp including an annular element having a first set of fingers extending from the annular element in the first direction parallel to the central axis of the annular element, the first set of fingers providing a radial force on the inside edge of one of the disks, and the clamp including a second set of fingers extending from the annular element in a second direction parallel to the central axis of the annular element and opposite to the first direction, the fingers of the second set being for imposing a radially force on an inside edge of a second disk. In another embodiment, a disk drive information storage device with a pair of disks includes a spindle motor having a rotor which includes a disk-shaped portion having an outer diameter, and an upper surface for supporting one of the pair of disks. A second one of the pair of disks is connected to the rotor on a side of the first disk opposite the spindle motor. A clamp having an outer diameter smaller than the outer diameter of the disk-shaped portion of the rotor is connected to a cylindrical portion of the rotor between the first and second disk. An actuator is provided to support first and second read/write heads, with the actuator being movable to position the first and second read/write heads such that the first read/write head reads information from or writes information to a portion of a second surface of the first disk between the outer diameter of the disk-shaped portion of the rotor and the outside diameter of the clamp. In one embodiment, the disk drive information storage device comprises a housing having a footprint that includes a first dimension of about 35 mm. In another embodiment, at least one of the disks of the pair of disks in the disk drive information storage device has a diameter in the range of from about 33 mm to about 34 mm.
