ABSTRACT:
A data transfer system for transferring data from magnetic tape peripheral units to a peripheral-controller for temporary storage and subsequent transfer to a host computer. A tape control unit, connected to the magnetic tape peripheral units, provides clock signals to a synchronization logic circuit which controls the transfer of data through two sequential latching registers to a buffer memory in the peripheral-controller. The two sequential latching registers function as a buffering delay element together with an automatic read logic unit which allows the read logic unit to use a lesser number of cycle-steal times than would ordinarily be required, while still controlling a steady uninterrupted flow of data words.
