Abstract

PURPOSE:To display a driving state of a magnetic disk, by providing a means for detecting driving state of the magnetic recording disk, and a means for displaing it, on an indicator of the magnetic recording disk. CONSTITUTION:When an electric power supply is turned on, an I/O control part 5 displays a state of a disk of a floppy disk device 3, for instance, ready (O) on a display part 7 of a CRT display 1 through a floppy disk controller 4, also gives a data write command to the controller 4 in accordance with a write instruction from a CPU6, and also displays data writing (W) on the display part 7 of the CRT display 1 through a CRT controller 2. In the same way, reading (R), seeking (S), retry (T), error (E) and alarm (X) are displayed. A display part 8 is used for the second disk device, and a display part 9 is used for a warning.
