US Patent:

62923277, Sep 18, 2001

Filed:

Oct 14, 1999

Appl. No.:

9/418401

Inventors:

Walter E. Broom - Longmont CA
Mark A. Swenson - Lafayette CO
Lee Schultz - Arvada CO

Assignee:

Iomega Corporation - Roy UT

International Classification:

G11B 1702

US Classification:

360 9906

Abstract:

A disk drive has a frame for receiving and retaining a disk cartridge which includes a disk therein, such disk being rotatable about a first axis perpendicular to the frame and cartridge. An actuator is mounted to the frame and is movable a first lesser amount from a first position to a second position and a second greater amount from the first position to a third position. A retract/eject lever is also mounted to the frame, is rotatable on an axis parallel to the first axis by the actuator, and is biased to a resting position. The actuator upon being moved to the second position rotates the retract/eject lever into a head-retracting position. The actuator upon being moved to the third position rotates the retract/eject lever to the head-retracting position and then to a cartridge-ejecting position. A head assembly is mounted to the frame and is movable toward and away from the retained disk cartridge and the disk therein for reading data from/writing data to such disk. A head retracting assembly is mounted to the frame for retracting the head assembly away from the retained disk cartridge when the retract/eject lever is rotated to the second position.

US Classification:

369290

Abstract:

A retainer assembly (10) comprises a retainer member (24) and a spring (36). The spring (36) works in combination with a conical surface (34) on the hub (12) and a conical surface (28) on the retainer member (24). Depending upon magnitudes of defined angles A and W, the assembly (10) resists any axial force (42) that may act to disengage the disk (14) from the hub (12). The angles A and W are variable so long as a coefficient of friction. mu. between the conical surface (34) or the conical surface (28) and the ring (36) is greater than the tangent of one half the angle W.
