Title: Wayne A Rogelstad: Innovator in Data Storage Technology

Introduction

Wayne A Rogelstad is a notable inventor based in Rochester, MN (US). He has made significant contributions to the field of data storage technology, holding a total of 3 patents. His work primarily focuses on innovative methods for writing servo patterns in direct access storage devices.

Latest Patents

Wayne's latest patents include a self servo writing file and method for writing servo patterns in a direct access storage device. This invention provides a method where first servo information is written on data storage media 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. Subsequently, servo information is written on the data storage media in response to the detected servo signal reaching the predetermined value. The process of moving and writing is repeated sequentially until a second crash stop is reached. This method can utilize a quad-burst servo amplitude pattern or phase pattern for the servo information, making it adaptable for various servo options.

Another of his patents is the self servo writing file using the widest head. This invention follows a similar process as the previous one, ensuring that the servo writing method is easily adaptable for many different servo options. The method allows for variable track pitch by selectively varying the predetermined value compared to the detected servo signal.
