Title: Innovations by Ryan P. Mayo in Data Storage Technology

Introduction

Ryan P. Mayo is a prominent inventor based in Irvine, CA, known for his significant contributions to data storage technology. With a total of 11 patents to his name, he has made remarkable advancements in the field, particularly in the area of self-servo write circuitry.

Latest Patents

Among his latest patents is the invention of parallel self-servo write circuitry in a data storage device. This innovation describes example circuits, data storage devices, and methods to provide parallel self-servo write in a data storage device. The data storage device may include multiple heads actuated over respective surfaces of storage media, along with at least two preamplifiers and read paths to a channel circuit. Control circuitry may select heads connected through different preamplifiers for parallel self-servo write and receive read signals from the selected heads in parallel. These read signals, based on self-servo write reference spirals previously written to the storage media, are utilized to determine respective position error signals for the two heads. This allows for precise control of their respective positions with corresponding control signals to a shared voice control motor and respective micro and/or milli actuators on the arms supporting the heads.

Another notable patent is the preamplifier circuit for parallel self-servo write. This invention describes example storage preamplifier circuits, data storage devices, and methods for parallel self-servo write. The data storage device may include a pair of preamplifier circuits electrically connected to respective banks of read heads actuated over storage media surfaces. During read/write operations, each preamplifier circuit may selectively and sequentially provide read signals from a selected head to a pair of read channel interfaces. In self-servo write operations, each preamplifier circuit may selectively and in parallel provide read signals from a selected head in their corresponding banks of read heads to the pair of read channel interfaces.
