Latest Patents

Rhodes' latest patents include an ISO/IEC compatible digital audio tape digital data storage system. This invention provides a complete digital data storage (DDS) magnetic tape system designed for utilization with a host unit. The system comprises a host device interface for connecting the host unit with the DDS system, a controller/formatter for encoding and decoding data to and from the magnetic tape, and an automatic track follower (ATF) for performing automatic track following on the magnetic tape. Additionally, it features a driver for operating the magnetic tape, a read/write (R/W) channel for transferring data, and a read/write (R/W) head drum for data transfer, all under software programmable control.

Another significant patent by Rhodes is the digital data tape storage automatic track follower system. This system accurately positions the read/write head on the tracks of a magnetic tape. It includes a pilot signal generator for generating pilot signals from tape pilot marks, a sample-and-hold circuit for sampling pilot signals from adjacent tracks, and a comparator for comparing the magnitudes of pilot signals. A correction circuit centers the read/write head on the track being read, while a processor digitally controls the generator, sample-and-hold circuit, comparator, and correction circuit functions.
