He holds a total of 5 patents that showcase his expertise in digital servo control systems, particularly for disk drives. His innovative contributions have significantly impacted the field of data storage technology.
Latest Patents
One of Weilbacher's notable patents is a digital servo control system for use in disk drives. This system is designed as an "embedded" system, where servo control information is integrated on the same disk surface as user data. Unlike traditional embedded-servo systems that require multiple dibit pairs, Weilbacher's design utilizes a single dibit pair in a fractional positional error (PES) area. This approach allows the disk drive's read head to encounter only one dibit pair per sample period, thereby conserving valuable disk space for user data. Additionally, various pre-processing methods are incorporated to enhance measurement accuracy by compensating for non-ideal characteristics of the dibit measurement.
Another significant patent by Weilbacher involves a digital servo control system that includes a sample integrity tester. This tester is particularly beneficial for disk drives, as it filters out noise-corrupted measurements that could lead to erroneous calculations within the servo controller's control loop. If a measured position signal falls outside a predetermined window, the system utilizes a predicted value instead of the potentially spurious value. This allows the control loop to operate in a 'freewheel' (open-loop) mode, ensuring reliable performance.
