Abstract
An electronic circuit within a control unit for use with a remotely operated seismic tape recorder is disclosed wherein recording direction and motion are detected and retained for efficient data recordation. A seismic data recording system having some portions which are continuously energized and other portions having power switched off when not in operation retains information concerning recording direction, motion and track number to provide a smooth transition between inoperation and not in operation for the other portions of the seismic data recording system.
