Title: Edwin S. Busby, Jr.: Innovator in Video Tape Technology
Introduction
Edwin S. Busby, Jr. is a notable inventor based in Menlo Park, CA (US). He has made significant contributions to the field of video tape technology, holding a total of 2 patents. His work has had a lasting impact on the way video recording and playback systems operate.
Latest Patents
One of his latest patents is a method and apparatus for measuring the speed at which a tape was recorded. This invention features a tape speed measuring circuit designed for use with quadruplex video recorder/reproducers. It identifies the speed at which the recording was made, allowing for automatic switching to the correct speed during playback. The circuit measures the ratio of control track frequency relative to the capstan tach frequency to obtain the recorded tape speed. A commutating filter means responsive to the capstan tach signal enables the accurate extraction of the desired control track signal component at all tape speeds. Additionally, divider means count the number of tach pulses received during a selected time period, generating a high or low logic level based on the standard recorded tape speeds of 15 or 7.5 inches/second.
Another significant patent is the tape timer error corrector circuit for tape recorder/reproducers. This error corrector circuit is designed to correct a tape timer in a video tape recorder/reproducer (VTR) that has a multiple frequency control track. It separates a selected control track frequency from the composite frequencies using commutating filter means capable of following frequency variations caused by variable tape speeds. The filtered control track signal is phase compared with a tach clock signal of similar frequency obtained from the capstan tachometer. In the absence of slip, creep, tension variations, and other speed errors, there is no phase difference between the compared signals, allowing them to be phase locked together. Any phase deviations are detected and fed back to correct the tach clock signal, ensuring it accurately represents the passage of tape past the VTR head means.
