Abstract

PURPOSE:To reduce a control dependence rate onto a host computer by externally controlling a recording/reproducing means which records and reproduces data to a floppy disk via a microprogram control means. CONSTITUTION:A microprogram control part 12 interprets a simple instruction supplied from a host computer 1 via an interface circuit 11 and supplies the microcodes to an instruction executing part 14 for a series of writing/reading control jobs. The part 14 supplies the control data to a mechanical deck system controller 19 including a record/reproduction/erasion circuit 18, etc., according to the microcodes. The circuit 11 contains five types of registers including a 1-byte resetting register, etc. This register holds the reset data supplied from the computer 1 and resets individually a recording/reproducing means and the part 12.
