MidiStandardized SEG-D

MIDI is a SEG-D field data copy system providing the necessary tools to update your SEG-D library. It has long been recommended that digital data libraries be refreshed on a regular basis, with the figure of 10 years often mentioned. MIDI provides the opportunity to input the various historic versions of SEG-D and output standard SEG-D 2.1.

The SEG-D 2.1 format was recently ratified by the SEG Technical Standards Committee to improve support for high capacity media such as the IBM3592. The main aim was to allow the recording of multiple lines on a tape by use of a line sequence number.

Troika has developed a highly efficient SEG-D copy utility within MIDI. This crucial software provides the necessary tools to standardize your entire SEG-D library and transfer data from low-density, typically 9 track, 3480/3490 or 3590 to high capacity media (such as 3592). This package embraces the new SEGD 2.1 format which records a sequence number for each seismic line within a survey so that multiple lines may be written to tape.


MIDI can be interfaced to any standard SCSI devices via IBM/Windows drivers and "off-the-shelf" controllers including:

  • 9-track: 3480, 3490, 3490(E), 3590, 3592
  • Exabyte: 8500,8505, 8700
  • DLT
  • DAT
  • DVD
  • CD
  • etc.

Multiple drives may also be attached and run as separate job streams to increase throughput. MIDI includes support for a number of robotic devices including IBM3494 and STK9710, and also supports customized uploading of metadata to databases via XML.


A number of lists are created whilst transcription is being carried out, which may be used for quality assurance purposes, saving to disk, printout, etc. These lists include details of the data that has been read from and written to tape providing a machine-readable listing for import to a database, spread sheet for labeling, or documentation such as transmittals.
