This paper describes a flexible digital data recording and recovery system which will accept information of up to 76 bits per event at a rate variable from some 375 to some 48 Ã 103 bits per second (b/s), and replay at a rate of from 3 Ã 103 to 48 Ã 103 b/s. The total tape storage capacity is some 55 Ã 107 bits. The number of parameters recorded is limited only by the accuracy required and by the total event size (in relation to the maximum number of bits per event), provision is made within the equipment for correlation determination between selected parameters and for the selective examination of recorded data. The tape transport control system permits remote control which facilitates its integration into a computer complex. The system is illustrated by examples of its application to the acquisition of data from nuclear experiments.
