MEMBERS
  media_status
      Specifies the status of the media. See the DESCRIPTION section for the
      status values associated with the media_status member.

  unit_status
      Specifies the current status of the unit. See the DESCRIPTION section
      for the status values associated with the unit_status member.

  recordsz
      Specifies the record size, or 0 for variable-sized records.

  density_bpi
      Specifies the current density setting.

  density_bpi_wrt
      Specifies the density used for write operations.

  position
      Specifies the number of records that have been written since the last
      file mark.

  fm_cnt
      Specifies the number of file marks that have been encountered since the
      beginning of the tape.

  class
      Specifies the tape device class, such as 9-track or QIC.

  pad Specifies a reserved member.

  arch
      Specifies architecture-specific information, either a SCSI-specific
      structure or a character string.
