Title: The Innovative Contributions of Dana H. Brown

Introduction

Dana H. Brown is a prominent inventor based in Rochester, MN (US). She has made significant contributions to the field of data storage technology, holding a total of 13 patents. Her work primarily focuses on methods and apparatuses that enhance the performance and efficiency of direct access storage devices.

Latest Patents

Among her latest patents is a method and apparatus for servo positioning in a direct access storage device with a transducer read element width greater than one-third and less than one-half the width of a data cylinder. This innovative phase-modulated servo method ensures acceptable position linearity for servo positioning with a narrow transducer head in a disk file. The disk file includes at least one disk mounted for rotation about an axis, which has a surface for storing data and a transducer for writing and reading data and servo patterns. The transducer consists of a read element and a write element, where the read element's width is less than that of the write element, specifically greater than one-third and less than one-half of a data cylinder.

Another notable patent is the self-servo writing file, which provides a method for writing servo patterns in a direct access storage device. This method involves writing first servo information on a data storage medium at a first crash stop. The transducer heads are then moved offset from the written servo information while reading the last written servo information until the detected servo signal equals a predetermined value. The process of moving and writing is repeated until a second crash stop is reached, allowing for flexibility in servo writing options.
