Compliant Anchor For Securing Disk Drive Actuator Bearing

Compliant Anchor For Securing Disk Drive Actuator Bearing

US Patent:
5590002, Dec 31, 1996
Filed:
Jan 23, 1995
Appl. No.:
8/377033
Inventors:
Allen T. Bracken - Layton UT
Edward L. Rich - Ogden UT
Assignee:
Iomega Corporation - Roy UT
International Classification:
G11B 3314, G11B 554
US Classification:
360 9702
Abstract:
In a magnetic disk drive, a compliant member connects the top of the bearing assembly for the actuator arm to the drive. The member is compliant in the vertical direction and stiff in the horizontal direction to resist actuation forces being applied to the bearing assembly when the actuator rotates the arm. The actuator arm has a fork with a shelf on which the coil is mounted.

Method And Apparatus For Protecting A Hard Disk Drive From Shock

Method And Apparatus For Protecting A Hard Disk Drive From Shock

US Patent:
6496362, Dec 17, 2002
Filed:
May 14, 2001
Appl. No.:
09/858073
Inventors:
Ryan D. Osterhout - Layton UT
Scott P. Thomas - Ogden UT
Paul C. Kunz - Ogden UT
Allen T. Bracken - Layton UT
Assignee:
Iomega Corporation - Roy UT
International Classification:
H05K 502
US Classification:
361685, 361728, 248638, 3122232, 206586
Abstract:
An information storage device ( ) includes a cartridge ( ) which can be removably inserted into a cradle ( ) coupled by a cable ( ) to a host computer. The cartridge includes an outer housing ( ) containing a chamber ( ), and having an electrical connector ( ) on the exterior. An inner housing ( ) contains a hard disk mechanism, and is resiliently supported within the chamber by four resilient elements ( ). A flex circuit ( ) extends from the inner housing to the connector, and permits relative movement of the inner and outer housings. The resilient elements are formed by cutting a cross-shaped part ( ) from a foam sheet, cutting two square parts ( ) from a different foam sheet, adhesively laminating the outer parts to opposite sides of the center part, and then cutting the resulting assembly along two planes to form the four resilient elements.

Cam Mechanism To Clamp Magnetic Disk Against Cartridge Shell

Cam Mechanism To Clamp Magnetic Disk Against Cartridge Shell

US Patent:
5650899, Jul 22, 1997
Filed:
Oct 31, 1995
Appl. No.:
8/550818
Inventors:
Brian R. Schick - Eden UT
Allen T. Bracken - Layton UT
Edward L. Rich - Ogden UT
Wayne A. Sumner - Ogden UT
Assignee:
Iomega Corporation - Roy UT
International Classification:
G11B 2303
US Classification:
360133
Abstract:
A cartridge for a magnetic disk drive has a clamping mechanism which is actuated as the door to the cartridge is closed when the cartridge is removed from the drive. The door covers the opening through which the cartridge is accessed by read/write heads. When the cartridge is removed from the drive, the mechanism of the present invention clamps the recording disk against the cartridge shell to prevent rattle, which might otherwise damage the recording disk.

Drawer Loading Removable Cartridge Disk Drive

Drawer Loading Removable Cartridge Disk Drive

US Patent:
5216558, Jun 1, 1993
Filed:
Jan 30, 1991
Appl. No.:
7/647845
Inventors:
David Griffith - Layton UT
David Jones - Layton UT
Allen T. Bracken - Layton UT
Theon Rawlings - Layton UT
Assignee:
Iomega Corporation - Roy UT
International Classification:
G11B 1704
US Classification:
360 9906
Abstract:
In a disk drive the drive motor and actuator are mounted in a drawer which is slidable to an open position in which there is no vertical obstruction over the motor. The removable cartridge can be placed on the motor with the motor extending into the cartridge to engage the hub. A shutter in an edge of the cartridge is moved to an open position when the drawer is closed to provide access for the actuator to move magnetic heads into read/write relationship with the disks. A lock for the shutter maintains it in the closed position when the drawer is open.

Velocity Control For A Disk Drive Actuator

Velocity Control For A Disk Drive Actuator

US Patent:
5666236, Sep 9, 1997
Filed:
Aug 22, 1995
Appl. No.:
8/517836
Inventors:
Allen Thomas Bracken - Layton UT
Edward L. Rich - Ogden UT
Harold Lin Woods - Ogden UT
Hong Tan - Layton UT
Assignee:
Iomega Corporation - Roy UT
International Classification:
G11B 2102
US Classification:
360 75
Abstract:
A data storage device for reading and writing information to and from a storage medium and having an actuator for moving a read/write head over a surface of the storage medium comprises an optical sensor mounted on either a surface of the data storage device or a surface of the actuator, and a gray-scale pattern provided on the other of these surfaces, opposite the optical sensor. The gray scale pattern provides an amount of reflected light at the optical sensor that varies with the position of the actuator. The optical sensor receives the reflected light and generates therefrom an output signal indicative of the position of the actuator. A control system processes the position signal output from the optical sensor for controlling the velocity of the actuator.

One-Piece Magnet Return Path Assembly For A Disk Drive Actuator

One-Piece Magnet Return Path Assembly For A Disk Drive Actuator

US Patent:
5585679, Dec 17, 1996
Filed:
May 25, 1995
Appl. No.:
8/450691
Inventors:
Allen T. Bracken - Layton UT
Edward L. Rich - Ogden UT
Ted R. Davis - Oklahoma City OK
Assignee:
Iomega Corporation - Roy UT
International Classification:
H02K 4102, G11B 3300
US Classification:
310 13
Abstract:
A one-piece magnet return path assembly for a disk drive actuator comprises an upper plate, a lower plate and a plurality of standoffs extending between the upper and lower plates and establishing a pre-determined spacing between the plates. The upper and lower plates and the plurality of standoffs are stamped from a single sheet of magnetically permeable material that is then bent at predetermined locations to form the completed one-piece magnet return path assembly.

Disk Drive Cartridge Door

Disk Drive Cartridge Door

US Patent:
6252740, Jun 26, 2001
Filed:
Feb 18, 2000
Appl. No.:
9/506638
Inventors:
Wayne A. Sumner - Ogden UT
Allen T. Bracken - Layton UT
David W. Griffith - Layton UT
David E. Jones - Layton UT
Edward L. Rich - Ogden UT
Assignee:
Iomega Corporation - Roy UT
International Classification:
G11B 2303
US Classification:
360133
Abstract:
A cartridge for a magnetic disk drive has a rigid shell and a flexible door which covers an opening through which read/write heads engage the recording medium. The flexible door is guided outside of the shell to an open position as the cartridge is inserted into the drive. A projection on a flexible arm in the drive catches a hole in the flexible door to open it as the cartridge is inserted into the drive. The door along the outside of the cartridge conserves space so that the recording medium can be large for a given form factor drive.
