THE METHOD OF MAKING A SYNTHETIC SEISMIC RECORD TRACE IN ACCORDANCE WITH MEASURED OF ASSUMED REFLECTION COEFFICIENTS AND TWO-WAY TRAVEL TIMES FOR A SUCCESSION OF EARTH SUBSURFACE SEISMIC-WAVE-REFLECTING INTERFACES, WHICH METHOD COMPRISES SHIFTING EACH OF A PLURALITY OF SHIFTABLE MAGNETIC HEADS OF A MULTIPLE-TRACE MAGNETIC REPRODUCER TO ONE OF A CORRESPONDING PLURALITY OF TIMEDELAY POSITIONS MATCHING A SIMILAR PLURALITY OF TWO-WAY TRAVEL TIMES TO SUCCESSIVE INTERFACES, SCANNING PAST SAID HEADS A PLURALITY OF PRE-RECORDED MAGNETIC TRACES BEARING AN ASSUMED SEISMIC IMPULSE PERPENDICULARLY ALIGNED ACROSS SAID TRACES, MODIFYING THE OUTPUT AMPLITUDE AND THE PHASE OF EACH OF SAID HEAD OUTPUTS IN ACCORDANCE
