Title: Amy L Warner: Innovator in Disk Drive Technology
Introduction
Amy L Warner is a prominent inventor based in Rochester, MN (US). She has made significant contributions to the field of disk drive technology, holding a total of three patents. Her innovative work focuses on optimizing the movement of disk drive actuator arms, which is crucial for enhancing the performance and reliability of data storage devices.
Latest Patents
One of her latest patents is a method and apparatus for moving a disk drive actuator away from a magnetic latch that holds the arm in a parked position at the Inner Diameter (ID) of a disk. This invention involves a controlled energizing of the actuator motor to compensate for changes in magnetic holding force. When the disk drive is powered up, a current pulse is applied to the actuator motor to initiate movement away from the magnetic latch. If the initial sequence fails, the magnitude of the current pulses is increased to ensure successful movement. The read signal from the head is monitored to confirm that the arm has moved into the disk's central databand area and subsequently into the Outer Diameter (OD) area. The process is carefully controlled to gently bring the arm into contact with the disk drive's OD crash stop and then move it away, ensuring precise positioning at a selected track.
Career Highlights
Amy L Warner is currently employed at International Business Machines Corporation (IBM), where she continues to innovate in the field of disk drive technology. Her work has been instrumental in advancing the efficiency and effectiveness of data storage solutions.
