A magnetic matrix recorder

A single-transient recorder is currently being developed which allows automatic computer-compatible acquisition of high-speed signals. The heart of the system is a matrix of thin-film magnetic elements which is used to digitize and record the data. The present system samples at 5-ns intervals with six bits of resolution, is small in size, and can be operated in a fully automatic mode. One of the main recorder design considerations is the disturb current limit of the elements. This has been found to be a function of the recorded state as well as the width of the disturb pulse. The results of this project indicate that improvement of the matrix will be necessary for full utilization of the magnetic-matrix recording technique.
