Data Interchange Tape Drives
   (Half-Inch and Quarter-Inch Tape Drives)

Unylogix offers a complete range of half-inch tape drives in both traditional reel to reel (9 track) and 3480 (18 track), 3490 (18 track with compression) and 3490E (36 track) "square tape". Drives are available with SCSI or Pertec interface to allow attachment to almost any system type. We also offer quarter-inch tape drives with SCSI interfaces.
Half-Inch SCSI interface tape units are available with embedded emulation firmware (e.g. IBM 9348) to allow direct connection to systems which only support proprietary tape devices.

We also offer data interchange software to allow the transfer of data from one platform to another via tape - for example, a DOS or Windows based machine could be used to read tapes which were produced on a mainframe or to write tapes to be read on almost any platform.
