1. A transcriber system for receiving previously recorded seismic data in a first medium and outputting the seismic data in a second medium, comprising:

  • (a) at least on input means for receiving seismic data in the first medium, wherein the first medium can include either solid state memory or cartridge tape and wherein the input means includes data error correction means having first circuit means for detecting sync bits within a predetermined time window of the seismic data from the input means, and second circuit means for adjusting the dynamic gain of the input means until a sync bit is detected or the maximum dynamic gain of the input means is achieved;

    (b) output means for outputting seismic data in the second medium, wherein the second medium can include nine-track magnetic tape;

    (c) mode selector means for selecting a mode of transcription of the seismic data in the first medium; and
