Abstract
Data transfers between a host processor and a peripheral data recorder in a peripheral data storage system, such as tape recorder peripheral data storage system, are via a random-access buffer store in the peripheral data storage system and interposed between the peripheral data recorder and the host processor. A command queue storage in the peripheral data storage system stores commands received from the host processor for the peripheral data recorder. Additionally, apparatus in the peripheral data storage system form commands for transferring data between the peripheral data recorder and the buffer store without intervention of the host processor; both read transfers (data transfer from the peripheral data recorder to the host processor) and write transfers (data transfer from the host processor to the peripheral data recorder) are enabled via the formed commands.
