A peripheral-controller is used to manage data transfers between magnetic tape peripheral units and a main host computer. A program sequencer in the peripheral-controller can initiate an automatic read-write selection logic and control unit to operate in the "automatic write" mode whereby an automatic write-logic unit will transfer data out of a buffer memory in the peripheral-controller and into a magnetic tape control unit on a continuous basis without further instructions being required from the program sequencer.
