Method And System For Head Retraction In A Data Storage Device
US Patent:
6710979, Mar 23, 2004
Filed:
Mar 27, 2001
Appl. No.:
09/819012
Inventors:
Jeffrey M. Garrigues - Perry UT
Craig L. Rupp - Wellsville UT
Klinton D. Washburn - Willard UT

Assignee:
Iomega Corporation - Roy UT
International Classification:
G11B 2122
US Classification:
3602551
Abstract:
An improved actuation system for a data storage device. In one exemplary embodiment, a head retraction mechanism is movable in a head retraction direction between a head recording position and a head parked position, and an actuator remains engaged with the mechanism for movement during this movement to lessen the risk of damage. A torsional biasing member provides a biasing force on the head retraction arm. A displaceable transmission mechanism is driven by the actuator and moved in a slot in a base from a first position in which the head retraction mechanism is contacted and a second position in which an ejection mechanism is contacted. A load member is integral with the base contacts a friction member on the displaceable transmission mechanism to provide friction for this displaceable movement. The actuator is mounted between a stop member and a biasing member on the base.
Method And System For Shock Assisted Recording Head Protection
US Patent:
2002014, Oct 3, 2002
Filed:
Mar 27, 2001
Appl. No.:
09/818983
Inventors:
Jeffrey Garrigues - Perry UT, US
George Smedley - South Ogden UT, US
George Smedley - South Ogden UT, US
International Classification:
G11B021/02
US Classification:
360/075000, 360/256300
Abstract:
A data storage device comprising a carriage configured to hold a recording head and a locking system. The carriage is movable in a protected direction toward a protected position and in an unprotected direction away from the protected position. The locking system includes a locking member which is movable from a fully engaged position in which the carriage is restrained from movement in the unprotected direction, to a disengaged position in which the carriage is free to move in the unprotected direction to read and/or write data to a recording medium. The locking system is configured to move the locking member toward the fully engaged position in response to a force having a component in the unprotected direction. In one exemplary embodiment, the locking system comprises a linkage rotatably connecting the locking member with a movable member that comprises a solenoid.
