A small lightweight battery-operated tape recording system for gathering data on shipping and handling shocks experienced by containers was developed. A specialized magnetic tape recorder is used with six magnetoelectric velocity sensors mounted so as to sense impact velocity components in both polarities of the three principal axes of a container. By means of a four- channel recording head, the sensor outputs are magnetically stored on three tracks of 14-inch recording tape. The fourth track is used for time reference marks.
