Data Interchange and Data Conversion Systems and their use

The evolution of incompatible computer systems has led to the term of Data Interchange or Data Conversion being used to describe the transferring of data between different hardware platforms, operating systems etc. using specific media and peripherals, most commonly tape. 

The Mainframe tape units, such as 9 track (reel to reel) and 3480/90/90E 18 and 36 track cartridge, held information that needed to be processed by smaller computer systems. Major tape manufactures then produced low profile desk top tape units to satisfy this market opportunity, and specialist software houses developed tape data interchange utilities. This process was initially known as downsizing and later rightsizing. 

The early tape units were connect via their native Pertec interface using proprietary Tape Controllers and associated software. The introduction of SCSI as a standard interface for peripherals, allowed this early data interchange software to be further developed and made available for any tape device, including those intended for back-up, such as.DAT, Exabyte, DLT and Q.I.C. etc. This has expanded the market for data interchange between Midrange, Unix, Sun, NT, PC systems.
