Title: Richard D Barndt: Innovator in Digital Data Storage
Introduction
Richard D Barndt is a notable inventor based in Fremont, CA (US), recognized for his contributions to digital data storage technology. He holds a total of 6 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
One of Barndt's latest patents involves a digital data storage (DDS) system designed for reading DDS tapes. This system employs a partial response maximum likelihood detection system that utilizes redundancy in the 8-10 DC free modulation encoding to reduce low-frequency noise. The system incorporates a time-varying trellis decoder that embodies some of the PR1 rules along with the rules regarding the charge state or the digital sum variation (DSV) implicit in 8-10 modulation coding. The decoder effectively rejects low-frequency noise, such as that caused by crosstalk noise between adjacent tracks on the tape. Additionally, Barndt has developed a method for packing magnetic tape to improve pack stability prior to removal from a tape drive. This process involves completely unwinding the tape and then rewinding it without reading or writing to the tape, which reduces air entrainment and minimizes the risk of damage after removal.
